I am not sure how to go about integrating 24 babies with my existing small flock of 4. The four adults are three standard hens with a silkie rooster. The newbies I'm adding will include 12 bantams of various breeds and 12 standards of various breeds. The plan for final living arrangements is to have the standards and the silkie rooster in one coop (16 total) and the new bantams (12 or fewer, depending on number of cockerels) in a different coop. My issue is that the chicks are all being brooded together, so when do I separate them? The reason for the separate coops is chicken math. My husband built a beautiful coop last spring, but it isn't big enough for everyone when they are stuck inside during bad weather. It would be fine for sleeping only. We will have another coop within the next couple of weeks. Another question is about integrating a larger number of chicks with a very small existing flock. It almost seems like it could be easier to "integrate" the year-olds with the babies. I would like to change the existing girls and roo to the new coop because it will be bigger for them., although either coop could accommodate them. So my thought is to move the adults to be confined in the new coop so it becomes "home" and let the babies have the old coop. Then, after everyone has figured out where they belong, move the standard chicks into the coop with the existing flock, and lock them in for a few days while allowing the existing flock out. Would that work? Ideas?
