I have several White Jersey Giant roosters as well as one very noisy loud SilverLaced Wyandotte and they are like a choir of roosters. I can't get them to be quiet. The Silver Laced is in with three hens and crows almost constantly through the day then triggers the others to start in crowing. I'm trying to sell the Giants mostly but would like to keep a couple and the Wyandotte but he is so loud. Any tips on quieting them down or selling some?
