This is Phenix. He/she is almost 11 weeks old. Americana pullet according to tractor supply. I am worried she is a rooster. She bullies the other chickens and crows in the morning some times.
Neck feathers doesn’t matter much. But saddle feathers are the big tell. Plus the bright colors.The spiky neck feathers, the way they fluff out like that says cockerel, the crowing confirms it.
