How would I know which it is? The eye was so huge when he hatched I thought it was popped out of the socket. Over two days it returned to normal size, then yesterday started swelling again. It has a hazy film over it so I'm sure he is blind in that eye. No doubt it is painful! I was thinking of treating him with wormer in the eye and then orally, as is suggested on some other threads, just in case it IS eyeworm, but I don't know what the oral dosing would be on a four day old baby around the same size as a bantam chick. He's getting around fine, making it hard for me to get pics lol. I'm going to try to get some now. ETA: Here are pics from just now. It is about 1/3 of the size it was at hatch. Disappointing since it had gone down to normal size.
