Just this spring I bought 6 buff Orpington pullets from a local farm store. 4 of them have been growing just fine, but 1 has died and 1 of them seems to have some kind of illness that the one that died had. I would walk in to the coop and see it laying on the ground with a limp leg. I separated it just to be safe and kept a close eye. The leg doesn't seem to be hurting it, it just won't use it. I asked a friend and they suggested giving it electrolytes in its water. Any ideas as to what it would be? Or advice on what to do?
