Last week my husband told me he heard one of the roo's trying to crow. This morning I went out and my alpha roo "Keeper" (11 wk old Cuckoo Maran) was making a YEE-HAW sound trying to crow. Well, this evening, much to my surprise, I see him dancing around one of the Jersey Giant hens and then he tried to mount her! The roo is big, I measured him against the fence and he stands 16 inches w/o stretching his neck. ....aren't they a little young? I don't remember when the roo's started pouncing on my hens w/my last flock but it seemed to happen just before the hens began laying. But the hens are too young...?! Is this normal? Does this mean the hens are getting ready to lay??
