Hi. I have 16 chickens. 3 of them are roosters. All the hens are Australorps. 2 of the roosters are bantams. (one is d'Uccle Mille Fleur, other bantam is a black Cochin) The other rooster is a Big black Cochin. All of our chickens where together since they where 3 days old. They have always gotten along until about a week ago. They started fighting right about that time. They have been fighting daily and it's never been serious up until yesterday. They where all bleeding badly, and so I washed them up and separated them. We have 2 good size runs for them. During the day, I've been putting one rooster in each pen, and the other stays in the coop. At night they don't see each other so they don't fight. But during winter, they all have to stay inside all day. That's coming up fast. Plus I've been going through many swaps during the day so the ladies can get in to lay their eggs. This won't work for much longer, but I can't bear to see any rooster go. I have so many memories with them. They are all very sweet when they are not around other hens or roosters. Please help. Is there some kinda medicine you can give them to decrease their desire to fight? Like how catnip is for cats? I probably sound ridiculous but I'm willing to try anything in order to keep my roosters. Please help me. ~Rachel PS: please don't suggest culling if your trying to be helpful.
