So you are quite a lot out of ratio, which I know you're aware of and working on. In the time being I think you're going to have to separate the hens, as this could potentially cause fighting between the drakes. I'd personally keep Carl separate from the other boys, maybe with the hens, until...
Im sorry that happened, that's terrible.
I think we're going to need more details, diet, housing, space, and any hens? How many? Water to swim in? How much?
