I'm new to the chicken world, but have been free ranging an Americauna and a red sexling for about a month. I was told they were both hens and was anxious to start getting eggs. Recently the egg box bedding is showing signs of use, ( feathers present and matted down). The Americauna recently also started getting aggressive with the Red. Then yesterday, it crowed. I haven't heard this before. Do hens ever do this when getting ready to lay or do I have myself a rooster.
