I would like to have two coops of chickens. My goal is... 10 hens and 1 rooster Cream legbar in coop #1 AND 10 hens and 1 rooster Bielefelder Chickens in coop #2 These Chickens will come out to run the yard during the day and hopefully go back to the coop they grew up in for the first few months without being let out. Will these 2 groups of chickens merge into one or go about their business as 2 groups? Will the roosters fight for the others hens? What should I expect?
