Hi I have a buff Orpington rooster in a flock of 20 hens! He is constantly chasing the hens around! He's killed 2 of our baby guineas and the other day I caught him with his mouth around an older chicks neck slinging it around! I read that Orpington roosters are normally not as aggressive as other breeds so I'm confused as to what to do! Will he always be like this and we should butcher him? Or will he calm down at all?
