I just noticed today that one of my Australorps has a sore under her eye that looks swollen. I am thinking it is from one of the other hens pecking her since she is the bottom of the pecking order. I have never seen any of them be too mean to her, but it looks like this could have possibly been a sore that became infected. Does anyone else know if that is what this could be? If so, what is the best way to treat it??
I am very new to chickens so I really hope somebody can help me with this!
