My roo finally stopped crowing at 4 Am. He would wake up at 4 crow, then he would shut up for about an hour then start again and up for the day. Finally one day he crowed and we heard quite a racket from the coop, he shut up. Hasn't crowed that early since. I think the hens beat him up, to teach him to wait for at least the crack of dawn. I am just happy for him to wait for a bit...
