I have a 10 month old Rooster. He started crowing at about three months old. However he has never ever mated with any of my hens, he has never tried either, and he has the most horrible crow you’ve ever heard. My daughter and son-in-law who have had chickens for years, when they first heard him said, what in the world was that? LOL It’s that bad, he sounds like a teenage boy when their voices are changing. He also has Wry-tail.. He’s a White crested black Polish. I do have a big Easter egger Rooster named Rocky, and 14 hens and 4 pellets, and two duck hens. My big rooster mates all the girls, and tries to make everything else including the ducks. I don’t want my polish to mate, so I’m glad he doesn’t, because of the wry-tail, but I want to know why he hasn’t even tried. I’ve looked and looked online, but nothing. Is he one of a kind lol
