Has anyone else ever dealt with this before? It started this winter in some of our guineas. now it is hitting our chicks. It starts fast, almost overnight. They shut the eye with no swelling. They are not depressed, dont hide or show any signs of sickness. You do not know they have anything wrong till the eye bubbles out. And I mean a huge bubble! No foul smell, but full of white/yellow puss. If they live through it, the eyeball itself is gone. We treated with terramycin(sp) in the water. Over the counter Antibiotic injections, and it wont touch it. Out of 100 chicks, 9 have it now, I dont want it getting worse or taking over the whole flock. I did some reading last night, we are going to try the tylan 50 injected and drops today. Just want to know what it is, as our vet told us he is not a chicken vet. (in a nice way) First pic is the bad eye, second is the same chicks non affected eye.
