I bought 6 baby chicks from the country store. Two are New Hampshire Reds. Out of all 6 chicks one is different. This New hamshire has a red comb thingy in the top of his head and under it's chin, the other New hampshire doesnt have this, they are the same age. There is no crowing but I was wondering if this could be a rooster? This one also likes to stand off with the other chickens and bob his head back and forth (all cocky like) Without the crow is there any way I can know for sure? I think they are about 10 or so weeks.
