Gender Identity Problems

First, as you have read, there was Celie, the crowing hen. Celie no longer crows because, as again you have read, she hid out on me one night and the community 'coon had chicken for his midnight meal. The accompanying image, taken back in June, is of Joe as a young cockerel. He is now a sexually mature and active young rooster. But. Lately, after watching the pullets and hens on the nests where they lay their eggs, he has gotten it in his head to attempt the same. We sometimes hear the hens singing in cacophonous complaint because they want to lay an egg, but Joe is on their nest. Why can't my chickens be content with their gender? Maybe if I knew the answer to that question, I would know the answer to a lot of other questions. But I am clueless.
