One of our five chicks, a golden Seabright, started recently constantly goes after all the other chicks. Unprovoked.. They are now 6 weeks old. The sebright was a straight run......could that be a sign that he's a rooster? If so, I'd rather rehome it before the kids get so attached. I think it's too early to tell from feather/comb size, but I've attached a pic just in case. I know chickens are social, so it would be cruel to keep the sebright alone....any ideas on how to change its behavior?
