How do I introduce several chickens (not chicks) to my flock

You'll want to keep them separated by wire for a couple weeks so they can all kind of get used to each other before allowing them physical contact....the lots of space, multiple feed/water stations and places to hide/get up and away. there will be some pecking and fighting. Good Luck to yas!

Here's some notes I've taken on integration that I found to be very helpful.
See if any of them, or the links provided, might offer some tips that will assist you in your situation:

Integration of new chickens to flock.

Consider medical quarantine:

Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact. Integrating new birds of equal size works best.

For smaller chicks I used a large wire dog crate right in the coop for the smallers. I removed the crate door and put up a piece of wire fencing over the opening and bent up one corner just enough for the smallers to fit thru but the biggers could not. Feed and water inside the crate for the smallers. Make sure the smallers know how to get in and out of the crate opening before exposing them to the olders. this worked out great for me, by the time the crate was too small for the them to roost in there(about 3 weeks), they had pretty much integrated themselves to the olders.

If you have too many smallers to fit in a crate you can partition off part of the coop with a wire wall and make the same openings for smallers escape.

The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no blood drawn and/or new bird is not trapped/pinned down, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.

Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.

Places for the new birds to hide out of line of sight and/or up and away from any bully birds.

If you have enough space, (you are sure, cause you are more than doubling your flock) as they are all full grown, I would add them all at night and see how it goes. Because you are adding an established flock to and established flock each set of birds will have a pecking order and friends. Really multiple bird additions in my experience are the easiest, especially if you have an established rooter.

Lean some pallets up against the wall, make sure there are roosts in the run, multiple feed and water stations.

I am not familiar with the cherry eggers? I am assuming that these are an egg producing cross, but are of a similar size as your current birds?

I agree with Mrs K. Quarantine or not will depend on your personal comfort level. But adding a flock to a flock is much easier than adding a single bird to a flock. I'm more of a get-it-over-with type in this case. There will be some squabbling, of course, and make sure there are hiding places in case a bird is singled out. Plan on utilizing food to distract them some. If the other hens have never been with a rooster, that may take some adjustment on both sides, but he'll bring them into line fairly soon. They may always live as two seperate flocks, but live should be fairly harmonious after the first few days.

Cherry eggers are another term for production reds

 

I added 3 new RIR hens to my existing flock of 3 RIR's, 2 BO's and a BO Rooster recently. I put them into a cage outside for a few hours so the old flock could stare at them for a bit (!) - (bless my rooster's heart, he was dancing around the cage for them!) - and then once it was dark, and the old flock had gone to bed, I put the new girls on the roost with the old girls and hoped for the best.

I did not do any quarantining but I got the new girls from a hatchery, so I considered the stock to be clean. Under any other circumstances I would definitely keep them separated to ensure there was no transfer of disease. One thing I did do (despite the new girls looking great) was dust them all for lice and mites, and worm them before joining them with the flock.

There was some minor pecking and chasing, and the older birds blocked access to the feed and water which was easily fixed by installing more stations. You are in a fortunate position in that you are adding a greater number of birds to your flock than what you already have, so the likelihood that one bird will be singled out for bullying is slight.

They will probably run as two separate flocks for a while - mine did not socialise much for about 3 weeks and they stuck with their friends for that time, but eventually they merged into one flock. I did not free range them for a few days, in the hope that forcing them to be in close proximity would make them establish as a single flock - and it seemed to work.

Good luck! It will all work out in time. Just allow them to have their little squabbles as they need to. If you interfere with that process it can extend it.

Quarantine the chickens for about a a week, if there appears no signs of illness, put them in the coop. When you put them in the coop, place them in at night, so in the morning, they wake up and just think they're suppose to be their. Expect to see the pecking order in action.

 

Yep, that makes great sense!!

But.... it will not be a true biological quarantine, just an integration separation, you need them quite a distance apart for a true bio QT.
Read about medical quarantine in the links in my other post above.

When you remove the coop partition, I'd leave the temporary roost (and the extra feed/water) for a while, until you see them all using the main roosts.
It will remove 2 sources of stress(sustenance and sleep) from the flock integration.

Having a coop partition was priceless when I had to separate a nasty cockerel last winter and when I added new chicks this spring.
I left the partition roost up and the littlers all used for a few weeks, then lo and behold they started roosting with the older birds in the main coop.


I don't 'do' crawling anymore either, laughed hard at that one!
