I remember calling my friend, and fellow flock owner, many years ago with this question, "What is the best way to add my new chicks to my flock?" She kindly shared some quite helpful suggestions! Adding new chickens into your existing flock can be both exciting and stressful. Whether you're introducing cute six-week-old chicks or established adult birds, the process requires thoughtful planning. Sharing from my own experiences, I hope this post provides some practical tips and examples that help you introduce new flock members without ruffling too many feathers!
Start With Understanding the Existing
Pecking Order in Your Flock
Although I am not one to pick up my chickens, I absolutely love to watch my flocks. It doesn't take long to notice which 2-3 hens have an inseparable bond, the hen that others clear a path for, or the shy gal in your flock that seems to "fly solo" most of the time. I can't even start to type about roosters! I totally love good roosters. That is a post for another day. For now, let's focus on how the hierarchy amongst your hens can maintain order and social structure within your flock. As you spend time with your feathered friends, you might notice some quirky behaviors that reveal their pecking order. Recognizing these behaviors will help you better understand the dynamics of your flock and prepare for any integration efforts you may consider in the future. Here are some fun signs that show the current pecking order within your flocks:
Queen of the Flock: The dominant hen often gets first dibs on food and the best nesting spots, and she’ll let everyone know it! When she comes up for scraps, or anything she has a fancy for, you'll notice the other flock members give her space. If they don't notice her royal presence, she will likely make them aware quickly. Now, this gal is not a mean hen, she is just at the top of the pecking order. All of these behaviors are normal and actually add to the little community within your flock.
The "Pecking" Order: You might witness a little peck here and there, especially when one chicken tries to assert its place in the hierarchy. A little squabble over treats or space can be common, but it’s usually harmless and just a way to establish who’s got it and who doesn't. Hens higher in the pecking order may also occasionally remind lower-ranking hens of their status by chasing and literally chest bumping into them. A good rooster will quickly run in and break up these little quarrels. (Had to add in one good rooster trait here!)
The Cool Chicks: Have you noticed how some hens tend to stick together while others roam solo? Those groups often reflect the pecking order. Usually, these little groups within your flock are higher in the pecking order. Interestingly, my hubby and I have both commented on how these groups are often of the same breed when within a mixed flock, but not always!
Ruffled Feathers: Have you ever noticed a hen flare her neck feathers, puff out her chest, or stretch her wings out in front of or towards another hen for seemingly no reason? These aren't just stretches; she is strutting her stuff, aka asserting her dominance! (Although I still think they may be stretches sometimes, haha!)
Dinnertime Drama: The dominant hen will not be the only one that pushes her way to get her share of feed or treats first. Those that have a higher position in the flock will also eat first. You can easily tell who holds a lower station in the pecking order as those gals won't even attempt to get their portion until the more dominant hens are done.
Ruling the Roost: Higher-ranking chickens often claim the best spots on the roost, while lower-ranking chickens settle for less desirable areas. This is a good example of why having enough roosting space is important. It may seem like there is enough space on the roost for more gals, but some subordinate hens would rather sit on the floor of the coop than assert dominance right before bedtime.
Birds of a Feather: It is also important to note the breed(s) of your chickens. While each hen has her own unique personality, their genetic traits can affect how they interact within their flock. That said, our Barnyard Mix flock queen is an older Buff Orpington. She is actually pretty gruff with her subordinates at times, despite being a breed known as docile.
A little about me:
I don't hold my chickens. What's up with that? I know! Haha! Many chicken people love to hold their chickens! It isn't my thing. Unless it is for a pen move, skootching a hen off the nesting box, or holding them for their NPIP testing, I won't be out there carrying my favorite hens around. Why? It is 100% personal preference! I don't know why. Haha! I do love my chickens, though! I am delighted to see them run around & display the above mentioned behaviors, feed them their favorite treats, and ya....I talk to them constantly!
Prioritize Flock Health:
Consider Quarantining New Arrivals
Regardless of their age, it’s a good idea to monitor your new arrivals before they join your flock. Depending on where you got your new feathered friends from, you may want to keep them separate for 1-8 weeks. This quarantine time can help catch any potential illness early on, keeping your entire flock safe and sound. During this time, observe their behavior closely. Look for signs such as lethargy, lack of appetite, or if their droppings seem abnormal. This is also a great opportunity for you new flock members to get to know you! After all, this is also their new home. Hopefully, you will not have to worry about any of these things, and your new feathered friends will be right as rain!
Consider the NPIP Program
If you’re on the lookout for new birds, consider purchasing from farms or hatcheries that are part of the NPIP (National Poultry Improvement Plan) program. This initiative helps ensure that your new feathered friends come from breeders who prioritize biosecurity and health. Whether you decide to go with NPIP-certified birds or not, remember that giving your new feathered friends a separate space for a bit of time can make all the difference in keeping everyone healthy!
About Us & NPIP (National Poultry Improvement Plan)
Our flocks are NPIP Certified Clean. What does that mean? The National Poultry Improvement Plan, NPIP, is a voluntary program that's overseen by the USDA that monitors the health of flocks and hatcheries. Twice a year they test our birds to confirm they are clean of Salmonella, Pullorum-Typhoid, Avian Influenza, etc. They also inspect the birds' housing and feed storage to ensure it's clean and rodent free. With every chick or hatching eggs order we ship, we will send you the NPIP clean information.
In order to maintain our NPIP Certification and for the Bio-Security of our flocks, we do not offer tours or visits to our farm. Even before we became NPIP Certified Clean, I personally chose to only add flock members from other NPIP certified flocks. With our certification, I now can only add birds from other certified flocks. You can read more about Our Flocks Here. :)
Introducing Chicks (6-12 Weeks Old) & Adult Hens
Haha, I initially planned to include a separate section on introducing adult birds to your flocks, but many of the same principles and minor adjustments apply to birds of all ages! To keep things simple, I will primarily refer to introducing chicks or young birds. These tips will help with grown gals, as well!
Gradual Introduction & Creating a Separate Space
When introducing chicks, I keep the them in a separate area alongside the adults. I give them a few weeks with only a visual introduction, "Gradual Introduction." Being able to see and hear each other without physical contact can help the chicks and their soon-to-be flock to get to know each other without bullying or injury to the young birds.
To gradually introduce your new flock members, you will need a separate space for them. It can be simple and temporary, or you can set up something that works well for future use. If you have the space, a separate coop or a fenced-off section in your chicken run will work well for new birds to adapt to their surroundings without directly interacting with your existing flock. If you only have a few hens to introduce, a small kennel or hutch within your chicken run does the trick, too!

What age should the chicks be when they join the flock?
What is the best age to integrate new flock members? Personally, I wait until the gals are 8-12 weeks old before I add them in with their new flock. By this time, my chicks have spent the majority (if not all) of their brooder and grow out time with their new flock surrounding them. It usually ends up as a fairly seamless and smooth transition. Haha, in fact, it oftentimes ends up that the chicks are more than happy to explore their new digs and finally be with the big girls! The hens don't seem to take much of an interest in their "new" flock mates other than a little peck or stance when the little gals run around and into their space a bit. Having that time, although technically separated, really does help get the gals all to know each other. That said, I know that we all do not have the space or set-up to have such a long introduction. Your flock and setup may warrant a different time frame that works well for you and your feathered friends.

Time for Chicks to Join the Flock
Here are a few things I do to reduce stress and make for a peaceful transition when it is time to blend new members into my flock. (These points will not only help with the initial interactions, but they will also help keep the peace within your flock dynamics moving forward.)
Gradual Introduction: Allow a minimum of 1-2 weeks of "Gradual Introduction" as mentioned above.
Room to Spread Their Wings: This is something to take into account aside from knowing how many chickens your coop/run can accommodate. Do you have extra space within your coop and run where your newest flock members can get away from older or more dominant hens? If your chicken run is rather open, think about breaking up the space a bit. Even placing something as simple as a chair in the run can break up the space a bit. It also gives a roost or place to duck under if an older hen decides to get a bit too rowdy.
Chicken Scratch: Treats, hay, watermelon chunks, and the like, are all great distractions for your flock, just to name a few. You know your flock! If they have a favorite treat, now is the time to spoil them! (My personal favorite is hay semi-spread out with dried grubs scattered in.) The gals will be so interested in this yummy and interesting distraction that they may not pay attention to the newcomers at all.
Remember That Dinnertime Drama: At the beginning of this post we talked about flock dynamics. That dinnertime drama still applies. To make things less dramatic for the time being, consider adding an extra feeder and waterer for a week or so. The extra space for your flock to spread out a bit will reduce stress until the new peeps in the pecking order are somewhat established.
Do you have the time? Choose a day that you have time to observe and check in on your flocks often through the day. Although things will likely go well, it is better if you are there to make adjustments if needed.
Patience: Integration is a process that requires patience. Some flocks adapt faster than others. If conflicts seem severe or prolonged, don’t hesitate to pause and try again later. Part of why I generally wait until the 12 week old age before adding new members to a flock is because I have had to take a step back, reevaluate, and start over with younger additions. If you see your newest flock members hiding in the coop all day, darting around vs walking, and never seeming to relax, you may want to allow more time for a gradual introduction for this new group of gals.
Time of day: My preferred time of day for flock integration is afternoon to early evening. The time depends on the temps! If it is a hot day, I wait until early evening when the chicken still have plenty of awake time, but it is cool enough that they are scratching around and enjoying the evening. In cooler weather, I often will add the new members earlier in the afternoon.
Nighttime Note: Many suggest integrating flocks at night by simply placing the new flock members in the coop after dark. Chickens do not see well in low light, so this does make for a peaceful night. I have found that younger birds seem to be more stressed for a longer amount of time with this nighttime method, and some end up being in the coop most of the day even as adults. When I add just a few hens or young birds to a flock, I like to take the time to integrate them during the day as previously mentioned.
***When combining my adult flocks for easier care over winter, I use this nighttime method. I use this nighttime method in combination with having the other bullet points covered. Of course, these flocks have shared a fence line or been neighbors in the pasture chicken tractors all season. They know each other. :)
Continue to Monitor Behavior: After you've added in your new peeps, keep a close eye on interactions for the following days. It’s normal to see some pecking as they establish their hierarchy. It is the "pecking" order after all, so not all negative interactions need to be addressed or even worried about. However, if you notice excessive aggression, you may need to make adjustments. Think about the easy adjustments you can make to the run, like in the bullet point "Room to Spread Their Wings."
Examples from our farm: Extra run roosts, "treats" like weeds from the garden, a small introduction coop in a run, and our chicken tractor
(Notice the hen and chick? She is a lovely gal that was insistent on hatching a clutch.
She found a good hiding spot and hatched this little one with the flock!)
My Conclusion
Successfully integrating new members into your chicken flock can be fulfilling! I love to see new gals getting along with their older flock friends. Then I can focus on waiting for them to start laying! Haha! With preparation, close observation, and a little patience, you can create a thriving environment for both new and established birds. Remember, each flock has its unique dynamics, so trust your instincts! It's all about finding what works best for your unique feathered friends.
Here are some light-hearted tips that I hope help you along the way:
Observe and Adjust
Take the time to watch how your chickens interact. Each flock has its own dynamics within its pecking order. Be ready to adjust based on their behavior.
Patience
Just like waiting for a new layer to finally share her first egg with you, integrating new chickens takes time. Give them space to settle in and don’t rush the process. After all, good things come to those who wait...chicken people know this well!
Embrace Creativity
Feel free to experiment with different methods if you think that is best. There’s no one-size-fits-all rule book for chicken integration. Mix it up and see what works best for you and your feathered friends. In the end, trust your instincts and don't hesitate to learn from others. Sharing ideas can lead to learning and good results!
Enjoy the Experience
Remember to enjoy your chicken journey! Raising chickens should be a joyful experience. So, grab a cup of coffee, sit back, and watch your flock! Or pick up your favorite lap chicken and enjoy a cup of tea! Happy chicken keeping!
Thank you!
I hope that my experiences with my own flocks can help you in some way. I so appreciate all of you for reading, thank you!
Happy Chickening!
