I have a newly established flock of adult hens, bought them from October on and most are 1-2 years old. About a month ago I found a broody hen off her eggs in another nest box with both eyes swollen shut and was a little bloody. She's a banty and was broody in the favorite nesting box so my initial thought was her flock friends had been picking on her, my second thought was maybe fowl pox. Either way she was separated from the flock and made a full recovery after about 2 weeks in isolation. Yesterday I found another hen in a similar condition, unable to see out of both eyes, some sort of abrasion/wound to the side of her head (which I will be investigating further here shortly). She's isolated, eating and drinking fine but is obviously injured. We have had a lot of wild cats around the coop yard lately but I would be surprised if a feral cat would attack a full sized hen. My knowledge of pox is it's carried by mosquitos, I'm in Idaho it's in the low 20's and snowing so that doesn't seem like a possibility. With this being the second case I don't think it's another hen attacking them but I'm not sure what else could be causing this. The rest of the flock seems fine. I'm going to upload photos shortly.
