HELP!! I have 2 hens, the striped one and a broiler which I plan to eat soon. They are about 3 months old and have not been around other chickens for that length of time. About a week ago I noticed one was squinting one eye and had what looked to be peck marks around it. Now, her eye is runny and almost closed, which I was unable to get a pic of. The other eye is fine. I did get a pic of her comb, which is growing dark bumps. She is eating and drinking fine and running around, but may be acting slightly puny at times. Can anyone offer up what they think it might be? Should I go ahead and kill her and disinfect my coop?
