Thanks. I have separated her (she's an ameracauna) and we flushed her eyes and beak with saline last night, will do this 3 times/day for a couple days and continue to monitor. I still haven't heard her sneeze or cough but does seem like her "nose" is a bit runny. No bad smell though.
I'm new to chicken keeping, but a bit surprised at how quick many folks are to introduce antibiotics for a problem, often before a fairly good guess at what it is. Are chickens more resistant to getting superbugs than people, so antibiotic resistance is not such a big deal?
My natural instinct is to separate and monitor for awhile, give good food/fresh water with electrolytes before resorting to antibiotics. Is this a bad approach? Eg if my chicken does have crd, does it NEED to be treated with antibiotics, or can we just keep her warm and dry and this bout of the symptoms will pass on it's own in a few days?
Thanks for all the advice on here!
