I have a chicken (almost 4 years old) that has had an injured foot and has been having to stay inside until I can finish her separate cage. I change her bedding twice a day but I noticed her eyes looked a tad bit different as if there's some cloudiness to it and first thing I thought of was the smell of ammonia possibly causing it. Obviously if it was too bad of a smell, I wouldn't be able to stand it in the house but have been turning on the bathroom fans as well when I change the bedding pad. If it is ammonia causing her eye to look a little different, what treatment do you suggest? Would using clear eyes eye drops for humans be okay to put a drop in each of her eyes?
