Introducing 3 New Hens To Our Flock

We currently have 2 hens – A Bluebell called “Sienna” and a Black Rock called “Phoenix” – both are laying machines and we get close to a dozen eggs a week from them.

Sienna has always been the dominant one – and a little bit of a bully.

A week ago a friend came to me and asked if I could look after his 5 chickens for a month. He was in a desperate situation and so I really couldn’t say no.

Introducing new hens would be seen as a challenge to Sienna’s authority. And I was expecting a few pecks here and there as the ‘pecking order’ was re-established or should I say reaffirmed in the case of Sienna.

What I wasn’t expecting was just how violent it would be!

I have read much about the topic of introducing new hens to an existing flock and there are a few different schools of thought out there. Some people recommend you wait until it is dark and the existing hens have put themselves to bed.

They then introduce the new hens into the chicken coop. You the owner would decide where in the coop they will sleep for the night and you pretty much put them down where you see fit.

Others suggest a more staggered introduction. The idea is to keep them separated but ideally within eye contact over a course of a few days to a few weeks. This gives them time to get used to each other. They should not have any physical interaction during this period.

There is also the point that keeping them apart for a longer period lessens the chance of disease being spread.

I guess you can never be certain whether or not your new birds are carrying anything, and at least if you keep them separated for a week or so, any disease or problem should make its presence known and you can deal with it before spreading it amongst your existing flock.

You should also always try and avoid introducing just one hen as this can lead to the flock taking exception and all having a go at the new arrival.


I arranged for the hens to be dropped off at dusk. That way everyone would be less stressed out as chickens tend to be less active and more calm when night falls.

Luckily I have a spare ark that I popped them in for the night and that was that. Sienna and Phoenix had put themselves to bed so weren’t really aware of the new arrivals.

The next morning I was up early to watch and see the action. For the most part our two just minded their own business. But later on as they approached the ark it became evident who the dominant hen was in each group.

After a few more days of rotating the 2 groups between the ark and the large enclosed run I decided to release two of the new hens into the pen with our Bluebell and Black Rock.

Sienna straight away had a go at them but it wasn’t too serious and there was no fighting back from the two new ones.

I kept the dominant one of the new group inside the ark to give both dominant hens more time to get used to each other. After a day or so the other 4 had integrated well enough, with the odd peck here and there from our dominant Bluebell.

But I still had two very aggressive hens not willing to relinquish their status in the pecking order.

After now almost 6 days together I decided it was time to settle this once and for all. I released all 5 together in the morning and for a while they were all busying themselves with filling their crops.

But eventually paths crossed and they caught sight of each other and the fight was on.

It didn’t last as long as I had thought it would and luckily there wasn’t too much damage done. A little bit of blood drawn from the comb of the newcomer but I remedied that with a mild antiseptic spray. It was shocking at first to see the bird bleeding but the next day it had healed.

That night all 5 went to sleep in the hen house together. I made sure Sienna was the last one to go to bed. I put her in the ark and waited to well after dark. When all had settle in for the night I moved Sienna from the ark back into the hen house and plonked her next to Phoenix and watched with a torch light to see what would happen.

As previously stated – after it gets dark, hens become docile, and there weren’t any problems apart from a bit of hasty movement from the hen that had taken Sienna’s favourite roosting spot.

The following morning while it was still dark I went down to check on them and they were already out and about. No doubt as soon as Sienna stirred the others thought it was probably best that they got out of her way!

Sienna has had a few more goes at all three of them during the course of the day but none of them stand up to her and they all manage to get away without any injuries. So I guess the pecking order has been successfully established!

What did I learn from this experience?

  • It was a lot more violent than I was expecting – I really was quite shocked at the sight of blood on the comb of both hens.
  • It took less time than I have thought. When the two hens were having a go at each through the wire of the ark I honestly thought I had a much bigger problem on my hands.
  • The fight didn’t last as long as I had thought it would and luckily there wasn’t too much damage done. A little bit of blood drawn but I remedied that with a mild antiseptic spray and by the next day it had healed.
  • And finally not to bet on who you think will be the top of the pecking order. My money was on the new hen that had previously been in charge of 6 others and had the battle scars to prove it. I was expecting Sienna to quickly get put in her place. But the complete opposite happened.

  1. I am going to pick up my 4 new hens next week. They have been reared on the same farm, but not in the same pen. 2 Marans and 2 Welsummers. I found the videos very useful and no doubt with my 4 there will have to be an establishment of a pecking order

  2. You guys are very very helpfull , excellent articles all through very detailed very nice. Thank you very much.

  3. Just watched the introduction of new hens to the existing group. Very interesting and will arm me with knowledge for the future.

    Bought your Devon coop and double run last week and being completely new to keeping chickens, have found all your information invaluable. Now waiting arrival of run cover then will go and purchase my chickens, can’t wait!!
    Many thanks

  4. We have three mature hens – a speckled Morans, a Rhode-Rock, and a Columbian blacktail. They are good friends, always stay close together and I couldn’t really identify any one as obviously dominant. We’ve just bought a new Devon house to replace an old (not so good) one and intend to buy three new hens very soon. I think the battle in the video was between two established matriarchs which is why it was a bit violent. I’m hoping that three young hens on point of lay will be more submissive and so won’t be attacked so violently.

  5. I have 3 bantams and over time have had to introduce a single new hen to the flock. My Frazzle has always remained the dominant one. My new challenge is introducing 2 ducklings! They are now 3 weeks old and have been taking advantage of this lovely weather to potter around the garden with the hens. So far so good. Next step is to try them together in the double run I have just bought. Taking it slowly with fingers crossed.
