I have an 8 week old silkie. She was sexed as female, and at 8 weeks old, looks very female (no spurs, very little comb, tail feathers grow down...). However, she has recently started crowing. Our adult females will "announce" when they lay, but they don't crow in the morning. She is the dominant female (or is trying very hard to be). Do females crow, or do we have a little roo? As cute as it is, she needs to stop, because we live in the city, and she will aggravate the neighbors. Any advice?
