I did do a search on this, I found out so far that an Andulusian (sp) type hen might crow. When I say crow, I mean "cock a doodle do" This morning I heard "cocka doodle do" really loud ! I have 2 red sex links and a mutt. Ruby is the boss (red sex link) could she have done that? I need a little verification on that it does happen? There are no other chickens in my area at all. At first I thought there was a wild rooster in my yard. No it was Ruby. Is this really true? I can't have a rooster for obvious reasons, I'm hoping it only happens once in a blue moon.
