Hi. I have a 3-month old white Silkie pullet that has been acting lethargic and one nostril was wet. I quarantined her with a heat lamp, fresh water & food and have kept her in there for a few days. She seems to be getting stronger every day. I did pick some 'boogers' off that nostril that past couple of days, but late yesterday and again this morning it's clear. We have had a LOT, and I mean a LOT of rain and I think she might have caught a cold or beginning of some other respiratory infection. Since she appears to be on the mend, my question is: When do I get antibiotics for a sick chicken? How long do I let a 'cold' or other type illness go before I run into town & buy them? Also, how long should I continue to keep her seperated? I was thinking of keeping her in there until we get the 2nd large coop up & can seperate my Silkies & Polish...I think the other chickens are kinda mean to little Sophia (White Silkie in question)...and I think they were preventing her from going into the coop during the rain!! Thanks!
