Can anyone help please? I have two buff orpington hens, we got these at approx 12 weeks old in September 2016. One of them has recently started behaving a bit like a rooseter, mounting other hens and calling hens over for food, however she doesn't crow. I would like someone to be able to tell me if they look male or female please. The one acting like a rooster is the one in the front of the pic.
