I have 3 older birds, about 23 weeks of age , 2 hens and 1 roo. Thats flock 1, then for flock 2 i have 1 roo, and 1 pullet about 15 weeks of age. They have seen eachother countless times through the fence and what not but I have had them together once, and it went badly, one of the older ones grabbed the rock and gave her a nasty wound on her neck. So i pulled them both quickly, she is still healing but is healing fast, so how do i get both of the flocks into one coop? Any help would be great. Thanks for reading.
