Is there such a thing as a non crowing rooster. Out of all 11 of my hens she/he (Blackie) is the biggest chicken I have they are all 21 week's old I got my first egg yesterday. He has never ever crowed once since I've had her. This morning I let them all out And blackie mounted a hand first time I seen her/him do this. Or maybe she's a hen taking over the male roll I don't know. I will have to post a picture. Thanks in Advance for any knowledge I get.
