4 week old chick came up with this growth on it's eyelid. Anyone have ideas as to what it could be and how to treat? It is not eye worm or an infection that i can tell. I thought it had gotten pecked on they eye and cleaned it off pretty well before I thought to take a pic. I didn't know what to do after i cleaned it, so just dabbed it with Blue-Kote to keep others from pecking it and put him back with mom.
