OK so I have three roosters. A white frizzled Cochin bantam, a red frizzled Cochin bantam and a splash silkie. My red can be out can be out with bother of them and he doesn't mate with the lady's. He will dancef or them but that's it. My white and splash don't get along so I rotate which days they can be out . So I'm wondering if both rooster's breed the hens for example one of my Black ameraucana hens how would the fertility work?
