I am discovering I have too many roos and debating on building separate coops for pairs or a separate pen for the roosters and take turns allowing the roos to be with the hens. I have Rhodes Islands, Leghorns, red and white Sexlinks, and a couple gray chickens, pair of Cochins and a pair of Americanas. The Americanas are already separate from others. There are some that I'm still not positive if they're roos or hens. If the neck feathers flare up and out and they fight others that look like roos, doesn't that mean they're roos?
