I have one Ayam Cemani rooster and 15 assorted hens on 1/3 acre. We live in the 'burbs and no one else around has chickens. I was hoping having a large harem and no competition would reduce his inclination to crow. My neighbors haven't said anything but the coop is near my bedroom window and I am not one of those people who enjoy the rooster crowing from 7:30am to whenever. I'm experimenting with putting him in my isolation coop at night because it stays dark in there and the sound is muffled. He's also learning to wear a no-crow collar. Is there anything else I can do?
