I removed two roosters from my chicken house and I appear to have a Delaware hen that is acting like a rooster. She is large and does resemble a rooster, but cant tell because all of the (14) CHICKENS are (17) weeks old and none have started laying yet. Here is a pic and the larger one is the one riding the hens. No crowing yet so didn't thin she was a HE? all in photo are the same age.
