I feel like my birds are never going to be healthy! Now that we're over the cocci, I went out this morning to find that my white polish pullet was asleep (head drooped but standing) in the corner. I picked her up, and one eye is totally crusted shut. The other eye looks fine, though it's not open all the way. She won't walk around, eat, or drink, but she's not laying down...just drooping her head. What should I do? Should I try to put warm water on the eye and de-crust it? Should I give her Tylan to fight infection? She's always been the weakest and smallest bird.
