So I think my hen Carmen has recovered from her respiratory illness. She became ill 8 days ago, with injection antibiodics started within 24 hours. She had Tylan 50 for a course of 5 days. At day four of treatment, she really had turned around - and I was reluctant to give her a last and final dose of Tylan, but I went ahead and gave it to her, basically because I didn't know what the best course of action was. So she appears recovered. NO SYMPTOMS and acting normal x 3 days. When is it safe for her to be around a mild-tempered silkie rooster, who will now be her new roomie. When is it possible for me to stop seeing her last, since she is still considered "contagious" until I hear otherwise? I want to get her back into a normal routine, as she is a two year old laying hen, that hasn't laid since she was sick - and now I get concerned that she will become impacted with eggs or develop a new health issue because she isn't laying like she would normally. She doesn't appear to be in a molt - still has all the feathers she had when she came down sick. Since it has been sunny the last two days, she has been put outside, in her very small crate for a couple of hours, more or less away from the others. The rest of the time she is locked away in a closet with a light and can move about. Sorry if this is a question that has been addressed before, but I really have tried to find out on BYC the answers to my questions - but it seems all the posts are about sick chickens or how to re-introduce chickens, but I can't find out anything about when she is considered ok to go back with/around the others. No one else developed an issue, but I am keeping a constant check on this.
