A few weeks ago I noticed my 8 week old (roughly) Silkie chick had a swollen eye. Thought it might be a pecking injury. Then I noticed one of my road island red chicks, around the same age, started sneezing. Couple of days later I noticed bubbles in the silkies eye. I have been treating her with terramycin for 3 days, it seems to be helping but not healing. I also started VetRx on the flock since TS was out of Tylan. I am going to feed stores today in search of tylan but I have some questions. My other two Red chicks are not showing any symptoms should I treat them anyways or not? Any other advice for me?
