My Rooster isn't even a year old, but he's big and healthy and has enjoyed being the ONLY male amongst 23 hens. He has a No-Crow collar because we have crappy neighbors. He still crowed, but it's stifled due to the collar- so all was good. As of two weeks ago, I realized I haven't heard much from him. He's eating, drinking, playing, and makes all other communication sounds, but his infamous crow hasn't been heard. Any ideas?
