I believe my chicks are about 8-12 weeks old. Today I just witnessed one of my supposedly "pullets" fighting with my three male barred rocks. She would harass them and even chase them while grabbing them at the their crown; she has drawn blood from each encounter and I was wondering if she's a male. She's a female "Ameraucana", but I kinda doubt that after researching the difference between Ameraucanas and Easter Eggers. I think the hatchery that I bought them from duped me. Anyways, is this normal chicken behavior? What should I do to stop this behavior and how can I tell if this chick is male? Any help would be great thanks.
