After day 5 of treating wry neck with vitamins b and e, and selenium, our chicken Pila began to show good results. Enough so that after another few days, when the weather became nice and she was very antsy, we let her rejoin her crew. We continued dosing her with the vitamins, but reducing the frequency to every other day. She began keeping her right eye half-closed, and now won't open it at all. I've looked closely at it, and don't see anything wrong - at most, I'd call it slightly filmy (but clear film). I've checked her ear on that side, and there doesn't appear to be any swelling. It does seem like there may have been some discharge (I know this only because her feathers seemed clumpy in that area). She doesn't LIKE me to be poking around on that side of her head, but doesn't seem to be in any pain. What the heck is this?
