well not completley bald... I have about 30 chickens that are around 3 months old mostly mottled cochins then there are some japs and barred rocks all bantam In one of my runs together these are the ones I'm tryin to sale.. These was from 3 different brooders. about 5 of the mottled cochins roosters all have bald backs and some have no tail feathers to very few. They had got picked at in the brooder thats one of the reasons I moved them to a bigger pen however they've been in this new pen for over a month and still bald no signs of blood or anything like the others are still pickin at them nor have I seen them.. what can I do to maybe help with the feathers growing back or put on them so the others don't pick at them, maybe there like youngins they act good while I'm around and once I leave they pick at each other..LOL anyhows any sugestions appreciated???
