How to Introduce New Chickens to Your Existing Flock

You’ve got yourself some chickens and now you’re looking to expand your flock. A new chicken is a feathered investment in your future, so it’s important that you follow the proper introduction procedures to ensure the safety and happiness of your chickens.

In this article, I will show you the best way to introduce new chickens to your flock. Without introducing them properly, they can injure each other.

Quarantine Before Introducing New Chickens

Chickens are susceptible to many diseases and parasites. To protect your flock from disease, you should quarantine new chickens for 30 days before introducing them to your existing flock.

Quarantine is the process of isolating a new chicken (or other animals) for a period of time to ensure that it does not carry any diseases or parasites that could be harmful to your existing flock. Quarantining new birds is particularly important if you have other chickens at home, but it can also help prevent the spread of disease in other types of animals.

The best way to quarantine new chickens is by placing them in a separate coop, run or pen. If possible, place this area away from the main part of your property so that they don’t come into contact with other animals on the farm or in your backyard. If there’s no way to isolate them completely, keep an eye on them until they’ve completed their quarantine period.

Introducing New Chickens Slowly

Introducing chickens to the flock can be a stressful experience for both the new chickens and your existing flock. If you’re bringing in new chickens, it’s important to introduce them slowly to avoid undue stress and injury.

The first thing you need to do is introduce the new chickens slowly. Start by putting them in a separate pen or other enclosure with food and water. This helps them get used to their new surroundings while also keeping them safe from aggressive birds in your flock.

Once they seem comfortable in their enclosure, move them into a small area with just one or two of your existing hens. Put some food and water out for them and watch how they interact with each other for about an hour. If all goes well, you can gradually increase their access to the rest of the coop over a few days by adding another hen at a time until they have full access to your coop.

Give Your Chickens a Proper Introduction

Chickens are social animals, and they need to be introduced carefully. You can introduce two chickens of the same sex together, but you should never introduce a rooster with a hen.

Introducing new chickens to your flock is a gradual process. You want to give them time to get used to each other before they are allowed free access throughout your coop. The first few days after introducing new chickens should be spent inside the coop with just one or two hens at a time. Then slowly increase their number over the next few days until all of the hens have been introduced and allowed outside together.

If you’ve purchased young pullets, don’t let them out until they are fully feathered (about 10 weeks old). Otherwise, it’s easy for them to pick up parasites from wild birds or even older hens in your flock.

How Long Will It Take Introducing New Chickens?

It takes time for the chickens to accept each other and they should not be forced together. It is best to introduce new chickens when they are young, with an age difference of no more than 6 months.

If you have two adult hens, when one dies, get a new one as soon as possible. This will help the remaining bird adjust more easily. The same applies if there are only a few hens left in your flock. If you have many hens and want to introduce one or two more, wait until they have settled down and then introduce them slowly over a period of weeks or months.

Chickens will recognize their companions by sight and sound; however, they do not recognize them by smell until they are around 8 weeks old. So if you have an older hen who has been outside all day, she will come back into the coop with her own smell on her feathers which may cause the younger ones to become aggressive towards her until they get used to it!

Some people recommend putting some old bedding from the coop into an empty dog kennel before introducing new chickens so that their scent is already present in their new home.

Special Circumstances When Introducing New Chickens

Introducing baby chicks to adults

Introducing baby chicks to adults chickens

It is important to know that new baby chicks should be introduced to the flock slowly and carefully. This can be done by setting up a separate pen for them, or by separating the chickens into two different pens.

This allows you to make sure that your adult chickens are not going to hurt or bully them.

Introducing adult chickens to baby chicks can be done in a few different ways. If you have more than one batch of chicks, you may want to introduce them all at once so that they can bond and get used to each other quickly.

If you only have one batch of chicks, then it is best if you introduce only one or two at a time.

Mixing Breeds

The key is to start out with a flock that is as diverse as possible. When you first set up your coop, add as many different breeds as possible so that they can get used to each other and become comfortable living together. Once they are used to each other, introduce new chickens into the mix slowly and carefully so that there aren’t any fights.

If you want to keep two separate flocks, then you can use the same method to introduce them slowly – put them in separate cages and let them get used to each other’s smells before letting them out together.

Tips and Tricks to Introducing New Chickens to Your Flock

Give Them Time to Get to Know One Another

Chickens live in flocks for a reason — having other birds around keeps them safe from predators and helps them find food. If you bring a new bird into their existing flock, the existing birds may view this as an intruder and try to chase it away. This can be dangerous for the new bird and stressful for everyone involved.

To help ease tension between your existing flock of chickens and your new baby chicks, give them time to get used to each other slowly. Starting with just one or two new members will help keep things manageable and give everyone time to adjust without overwhelming anyone too much at once.

Introduce New Birds One at a Time

If you have more than one new bird joining an existing flock of chickens, introduce them one at a time so that each bird can have time to get accustomed to its surroundings before being introduced to another bird. This will reduce stress on both sides of the introduction process.


When introducing new chickens to the flock, try to make the transition as easy as possible. Make sure you have plenty of time and that they are comfortable. Bring your new chicken into their coop and let them explore. Let them follow the flock as they do their normal routine, as long as it is safe for them to do so. The more time they spend with the other chickens in your flock, the less stressed they will be about them being around.
