This has actually happened to another chicken I had before. She was a black frizzle that was getting beat up by her peeps at the coop I had next to my barn in the country. So I brought her home (at the time was downtown Houston) so she could re-coop-erate in my backyard. She did relax and grew back her feathers and just kind of became the house bird. She laid an egg per day and then out of the blue began crowing, like a rooster. I assumed this was her way to becon a friend. After we sold our house I gave her to my mother who had a few chickens. They just hung out on her acre-big garden. Mom says she hasn't crowed since. Now I have 3 adult chickens all proven layers...no boys here. Well one of them began crowing this morning. Does anyone know why she (and my other one) crow? Do I have to break down and get them a roo? Is that what they want? All three are in a large, screened-in yard about 25X25 with a covered coop. Thanks for your input.
