Adding new chickens to an established flock

Chicken keeping can be an addictive hobby. When I got my first three birds I did not consider the possibility of adding to the flock. The steep learning curve that I went through on dealing with these feisty and adorable feathered friends made me realise how much pleasure could be derived from having a small flock of chickens running around the garden. By the time we suffered our first fatality I was feeling more knowledgeable and confident about many aspects of chicken keeping and wanted more.

I had learnt that chickens thrive in a flock and that a lone bird could suffer from a lack of friends. Introducing new birds to an established flock can be tricky, but bullying can be minimised if more than one bird is added at a time. The established birds do not then have a focus for their anger at having their territory invaded by interlopers. I decided that the best course of action would be to add two new birds to my remaining two to ensure that I would never have to deal with a lone and lonely hen.

That first attempt at introducing new birds taught me a great deal. As I had one coop and run they all had to sleep together, but this lead to what looked like vicious attacks. Adding new birds also risks passing on diseases as new and old will not have the same resistances. After a failed attempt at putting all the chickens in together at night and hoping they would simply wake up and accept each other, I divided the run with a bamboo criss cross fence and gave the new girls a pet carrier with improvised roosting bars to sleep in at the far end of the run. This arrangement was far from ideal but meant that the birds were safe and could see each other without being able to attack.

Chickens may appear daft but they are capable of breaking through fences when they are determined enough to get to the other side. Why did the chicken cross the road? Because she wanted to. During my regular checks I would find the old girls in the new girls area of the run and the new girls cowering in the old girls area. How these birds squeezed through the small gaps in the barrier I had created perplexed me and I would add more and more bamboo canes to the improvised divide. My attempts to keep them apart were constantly foiled.

After a few days I decided that this wasn’t working but, as no bird had been injured, I removed the barrier and let them run together. The severity of the pecking had subsided and, although the new girls still acted unhappy, they seemed to be coping. Over time they were accepted and their life became peaceful. I had learned that introductions need to be better managed.

Four chickens still didn’t seem like enough so when we were offered a stray hen that one of my daughter’s friends had discovered roosting in the trees in her garden we looked into buying a second coop. Finding just the sort I wanted available second hand in our area made me think that this was all meant to be. Once again I was wary of adding a single bird to the flock so I purchased one more hen. We moved the existing flock to the new, bigger coop and our two new additions went in the old coop. Stray hen didn’t take too kindly to the friend I had provided for her but things settled down quickly enough with no injuries sustained in establishing the pecking order.

We now had enough housing and big enough runs for fourteen hens. As we only had six I was itching to get more birds. We gave the flock a few months of sleeping apart but running together in the garden before we put stray hen and her friend in the big coop and purchased four pullets to put in the small coop. With two separate houses and runs available, introductions became easy and something we could now do annually with ease.

Hens start laying eggs at around five months old. Those bred to be commercial egg layers, the little brown hybrid hens, should then lay well for around a year. Although they can continue to lay for a further two years after this, their eggs may not be as strong shelled and their laying can be less predictable. Commercial establishments replace their entire flock after eighteen months as they do not wish to feed any hens that are not laying good eggs.

Pure bred hens are not kept for commercial egg production. These birds have a longer life expectancy and will lay well for longer, but go off lay through the winter months and have a tendency to go broody in the spring. In order to keep the lines pure, breeders will keep a close eye on the flock and cull any birds with defects. They will also ensure that birds are kept in separate enclosures so that matings can be managed. If new birds are to be added then they will be introduced as chicks.

Small, domestic flocks are therefore the only ones where birds of varying breeds and ages run together. I have been told that the varying ages and colours are a factor in bullying issues. If I wish to maintain harmony then I should entirely replace all my birds rather than adding just a few at a time and allowing the established birds to remain when they stop laying. I should also keep just one breed so that all birds in the flock look the same.

My experience has shown me that this is good advice but still I do not follow it. I like having lots of hens and we are very fond of our birds. I will only dispatch one if she gets ill and I cannot make her better. I currently have several hens eating my expensive feed and producing no eggs; they can be recognised by their shrunken comb. A laying head has a large, bright red comb. This turns pinkish and becomes just a little ridge on the head when a hen goes off lay.

I like little brown hybrid hens as I have found them the easiest to deal with. If I had my way then that is all we would keep but the rest of my family prefer variety. Thus we have brown, grey, black and speckled birds running around our garden. The variety does look very pretty but each acts differently and we do have occasional issues with broodiness and bullying. Giving the birds enough space minimises most issues as boredom and overcrowding can exacerbate problems.

Having put all our existing birds together in the big coop recently, we purchased four new pullets yesterday. At around seventeen weeks old they look very sweet and seemed to settle in well to their new home. I will be spending a lot of time with the flock over the coming weeks, ensuring that all remains well. As we drove to the farm that supplies us I reminded my husband and children that I wanted four little brown hens this time. We came home with two light sussex and two partridge leghorns. My daughter has named them after the angels from Supernatural and they are beautiful.

    A lovely and very informative post, thanks for sharing. πŸ™‚

    Really enjoyed this. I reblogged as it tied in so well as was so much more eloquent than my own blog post about introducing new hens. Who chooses their names?

    • zeudytigre says:

      Normally we take a chicken each and choose names that seem to suit. This time my daughter chose all the names though. She is a big Supernatural fan and was quite upset when all the angels fell in the recent season finale. She told me I could call them Gaby, Cassie, Bella and Lucy if there were too many objections to the biblical references!

    This helped me a great deal, thank you. I persuaded my parents to get hens last year (just as I was leaving for university, lol) and all the hens, despite being born approx March of last year, are STILL not properly laying. We got a teeny tiny egg last week and every few days we have one good egg – we sit outside and watch them for as long as we can to try and see who is laying but never seem to catch them as it is so infrequent
    However the comb tip is brilliant, thank you!
    I hope my parents will keep them, they’re getting fed up on wasting expensive feed and fencing on well fed pets. Makes sense πŸ˜‰
    Awesome post

    • zeudytigre says:

      Thank you πŸ™‚ If your parent’s hens free range then they may have made a nest in the garden. It is worth checking in quiet corners, amongst fallen leaves and under bushes. Mine often lay out of the nest box in the summer months.

      • Wawawr says:

        They have a large fenced in run to stay in instead, we were advised to keep them in it because of the exact reason you just brought up. The run is dirt and stones but not muddy, and they have so much room, a cosy dry house with straw and individual beds. for laying They eat layers pellets, maize meal, grass and plants (I often throw a few handfuls in) and healthy kitchen scraps.
        because of this I just cant fathom why they wont lay? We put the rooster in his own small pen with some corn at feeding time just to ensure that only the hens get the layer pellets (he has a bad habit of pushing his weight around a trampling the food.) So yes, they used to be free range (we have about a half-acre lawn in a very quiet countryside with a tractor passing every half hour) πŸ˜€ but currently not free range in hopes of a few more eggs! πŸ™‚
        Thank you ever so much for the suggestion though

    Loved this article and found it very helpful. I’ve been bitten by the chicken bug and am looking to add another 2 or 3 chickens to my existing 4 hens and cockerel. As the existing coop is only big enough for the 5 I currently have, I am looking to buy a second coop and house the new trio in there. In your experience, will the new hens roost in the new coop or do you think they will squash themselves in the old coop with the others? Thanks again for the article.

    • zeudytigre says:

      I would advise keeping the new hens separate but close for a period of time if you can. This ensures they do not bring any illness to existing flock, allows all birds to get used to each other’s presence, and means they will sleep in correct coop. Having said that, once put together all birds will ‘choose’ a coop if both available, not necessarily the one you think they should use πŸ™‚
