I posted about this earlier, and am noticing several other posts along similar lines. Thanks to those who posted possible causes - however, I was never able to figure what is causing the problems. Anyway.....the original "victim" did die, and a few days later, I noticed another chick with a foamy eye. I isolated him immediately, and treated him with oxytetracycline in his water. His eye gummed up completely, and was very swollen - the same as the other chick, and then the other eye became involved. HOWEVER.....rather than dying and being shipped off for necropsy - he is recovering. I still have him in my office (phewwww!), and he is eating, and drinking really, really well. Both his eyes are open and clear. He's been away from the flock for 8 days. Is it safe to reintroduce him to you think? Thanks for any advice.
