Roosters harassing hens is called foreplay. That's part of their job. 😂 Those Blues are beautiful. I've got Lavender eggs coming in a couple of weeks. Hoping for a good hatch.
The ameraucanas lay blue eggs. My other chickens like a brown. You will know pretty quickly if it’s a roosters. They out grow the hens pretty quickly. Hens make noises but I wouldn’t say they crow.
