We purchased 3 Barred Rocks, 2 hens and a rooster. Well, one died in a most unfortunate cage incident and we were just certain it was our Roo. Well, now our "girl" will occasionally crow (I have only heard it a couple times). I have to admit "she" looks different from the hen in size and color, but since we have had no crowing until now we thought she was just a bigger hen. They are about 21 weeks old. I heard that if you don't have a rooster sometimes the hens will crow but I think I am in denial. 2 weeks ago before the crowing started we added a 1 year old rooster to the mix to keep the girls safe while free ranging. So now I think I may have 2 roosters, uh oh! I have searched many pictures and I do occasionally see Barred Rock Hens with large combs, so I am just at loss. We are new at this if you couldn't already tell. My flock consists of 2 Barred Rocks 1 Golden Comet 1 Buff Orpington 1 Black Mottled D'uccles (roo) Then I have a separate coop for some Silkies The bird in question? Rosie Sue. This is our for-sure hen Matilda Blue.
