I can deal better with a roo that comes after me than goes after my girls. I started out thinking I'll just keep all the roos and I did for years. But if the one was mistreating the hens, out he went. I have had roos that protect the girls, let the girls have All the treats and eat first, warm the nest, and at night circle the coop making sure all the girls were in.
It's a fact of life that chickens get eaten and bad things may happen to roos. It's more humane to let someone process them and eat them. It's better than him being abused.
One important rule with roos. Never ever back away. Wear jeans and stand your ground. And make Him back up-a lot. It's rooster language for "It's rooster language for "I am the alpha roo, not you"
