I brought home four 3-week old Americauna chicks. I now know that they were sick when I bought them. One died during the first night. Now, two of them have eye problems. Chick #1 has an eye that is completely swollen shut. Chick #2 has one eye that is glazed over (looks blind) and the other eye secreting a yellow mucous. I have been wiping the eyes with a warm q-tip and I put tetracycline in their water (purchased at the feed store). I have neomycin eye drops (leftover from my cat) that I want to put into their eyes, but I don't want to overmedicate. Any information or suggestions will be GREATLY appreciate. I get way too attached to these little girls!
