BO hen 20+ weeks old, not laying, had cocci at 6 wk old, seemed to recover fully. Recently started staggering when she ran. And laying down a bit more. Thought it might be an electrolyte, vit, mineral deficiency so I started a suppliment yesterday. Today the red skin around her eyes is swollen, just slightly, and very red. No discharge from any where, poop seems a little runny but normal. She eats layer pellets, oyster shell, fresh veg and whole grain bread (as treats). Just to watch her graze she seems fine, and looks really good. If someone bumps her she falls over, if I come out, and they all run, she falls over while she runs It is a little funny to watch. But I'm getting worried since the suppliment didn't seem to perk her up as I had hoped. When I threw bread to them she caught some in mid air, so I know she has good vision, and is still some what coordinated. Any suggestions?
