Hi, first time chicken owner here. I have a flock of 11 of the easiest 22 week old pullets you could ask for, and my sister is giving me a 17 week old EE cockerel this weekend. I just want to know what to watch for as I introduce him to my girls. He is a quiet roo, rarely crows, and has been bossed around by my sister's head hen. I don't even know if I have a head hen. Aside from our one Salmon Favorelles being a loner in the flock, the rest seem to get along well. I'm hoping the young roo will fit in fine? Any tips? I can section the run off if needed, but not the coop. How would that work? What should I expect as we add him in? Thanks for any tips!
