I went outside to check on my hens today and found one who wouldn't open her eye. I tried to gently open it, and it looks like her eye is still there. There is no pus or cuts or anything like that on the eye, it seems fine besides the fact that it is closed. Above her eye/next to her comb there appears to be something wrong as well; it is dark and swollen in places. She is tilting her head so that her bad eye faces up more than her good eye, but I think that is just her trying to see better. She is also turning mostly towards her good eye, again I think because she is trying to see better. None of my other hens are acting strange, but I don't know what I should do with her. I had a different hen pass away for other reasons a while ago, but this hen is still eating and drinking fine and acting normal. I will post pictures once I get onto my computer!
