I am new at this. I got 4 chicks from someone new to raising poultry--don't know breeds, assume barnyard mixes. One black chick became a miniature rooster and crowed at 7 weeks (I didn't know this was possible). The gold roo is 14 weeks old. The black bird on the floor is 15 weeks old, very gentle, has the "rudder" tail that my full grown hens have. The one on the ice chest is 14 weeks, also small and docile but the tail looks like roo to me and the feathers have more green sheen. Is there any chance this is a pullet? I am trying to time transitioning them to the adult flock. Roosters are illegal so I need to do it before they crow. I'd like to wait for a break in the weather but also need to do it before I am down to one bird. The coop is heated, but one of my hens is surly and I'm afraid she would try to kick the young ones out.
