I have a duck. She lives with a rooster and a few chickens. She is very verbal and follows the rooster around a lot and seems to talk to the rooster every single time he crows and even bobs her head up and down as she is talking. the thing is she seems to have and eye infection in both of her eyes. at first I thought the rooster was pecking her and he does peck her beak if she seems to be talking "too much" but they are not bleeding. Also they seem to get a little better when she washes her fash thoroughly in the water. i have tried helping her clean her face but her eyes seem to have hard stuff on them. it does not wipe off easily. What can i use and does this sound like an eye infection?
