OK, so the serama chick was a "present" from the local chicken guy, and of course it turned out to be a rooster... though a very cute and silly one. I have been worried about him in the cold weather (we have been having dips to single digits here), and been ready to bring him inside in the garage. I also got him a tiny hen saver coat with fake fur on it just in case he looks cold... i know, nuts. So far, he's been foraging with the others, acting completely normal, chasing girls of all sizes, singing it full blast, not puffing up etc, and sleeps wedged between the bigger girls (i don't have a heated coop, but i have a heated roost). If he behaves normally, does it mean he's ok? how else can i tell?
