If SHE is a HE, then why wouldn't he crow by now?? Isn't that strange? Would this be why they are not laying eggs? Are you asking if they may not be laying because he doesn't crow yet? I don't think that would have anything to do with it. Are they all BO's? They can take longer than other chickens. I have all BO's too. Two finally started laying at 28 weeks, the other three have not started yet. They all are coming up on 31 weeks.
Yup that's definitely a rooster!
