I have a 21 week old Buff Orpington Rooster that still hasn't crowed!! What's the deal?? He was at the bottom of the pecking order for a while, and frankly, terrified of the hens. But he's gotten over his fear, for the most part, but while all my other roosters (in different coops. He is the only rooster in his coop) have felt a need over the last 4 weeks to show just how many times they can crow in a day, he is silent. He is the only Buff Orpington Roo that I have, or have ever had, so I don't really have anything to compare him too. Is it normal for a Buff Orpington Rooster to not be sexually mature at 21 weeks or is he a late bloomer?
