If you dont want to use a rooster collar and are permitted to have roosters, But don't want them/him yo crow at dawn. Then you can consider a rooster cabin. this is a dark and sound proof cabin for the night. The roosters sleep in it untill you get him/them out.
But do be carefull. You have to put enough pipes in for ventilation.
When the rooster goes to sleep with his flock, you can easily take him out and put him in the cabin.
This may work for when roosters crowing in the morning, but what about during breakfast time, brunch, lunch, mid afternoon, and evening? I have roosters that crow at all hours of the day.
I am allowed to have chickens, and have excess roosters from broods naturally hatched. Not usually a big deal, but Thanksgiving is coming up soon and one of my neighbors is having family from all over the country come to celebrate the holiday. I would go ahead and process them, but many of them still need another month to get to full size, and the processor likes to have at least 10 at a time to make it worth their while. I pay $5 each to have it done professionally.
