How young do roosters start..."feeling their oats"? I have a chick I thought was a hen, she's about 13 weeks I believe....possibly 14. She's never crowed, and she used to have a hatch mate of the same age that made a rooster squak when you picked him up..she doesn't do this. All her hatemates were killed, and she bullied the replacement chicks I got to keep her company (she's about 3-4 weeks older, but easily twice their size), so she's been braving it on her own with the older girls. Luckily she's growing fast, but they still chase her a bit. Today she was mating my RIR. Pulling out neck feathers, the whole nine yards. For a little bit, too, lol. I hesitate to say it's hen on hen dominence, because she's definitely the bottom of the pecking order currently. Is it too young for a Rooster to be doing this? Is Princess really a Prince?
