I have 8 1 yr old girls, all getting along and all producing. I'm considering getting a rooster. We have plenty of room, and now that I'm more used to life with chickens I thought it may be a good time. I have 3 silkies, 3 marans and 2 ameraucanas. My biggest questions are what breed do I introduce? Do I get a from a chick or young cockerel or buy a full grown guy? Thanks for any help, I need it!
