My Roo's were born I think May 1st, and they started to try crowing at 11-12 weeks. So good luck.
EEK don't tell me that lol
My Vinnie crowed a few times really early in the brooder, when we opened the garage and scared the daylights out of him, then not again for two months. Weird huh! I was glad though, it gave me time to decide whether or not I could keep him, after realizing really early that he was really a he!
