We have three black frizzle roosters. Originally, we thought we had 2 hens and one roo because their combs hadn't grown as much as the other. So this makes our flock of ten have four roos and 6 hens. It hurts to watch the evil trio attack the rest of the flock. The others are terrified of them and will not eat or leave the coop if they are out there. We have two white sultan hens, two japanese mottled hens, three partridge cochin (one roo and two hens) and the evil three. How do I stop this aggressive behavior and why are they doing this. Chipmunk, my other roo doesn't act like this. Please help! Or they are going to be dinner!
