I noticed that one of my silkie roosters had a runny-looking eye and mucus coming out of his nostrils. So I separated him from the other chickens and put him in a rabbit hutch with a silkie that was having eye problems. I know now that was a mistake since I don't believe they had the same sickness. Now the one that appeared to have a cold has gotten better, but I'm afraid to put him back with the other chickens since he has been exposed the the silkie with eye problems. It has been a few weeks and he hasn't picked up the eye problem from the other silkie, but could he still be carrying it? Is it safe to put him back with the healthy silkies?
