I have a chick that has started sneezing/semi hard breathing/head shaking but is eating normally and drinking normally..I talked to my vet and he gave me antibiotics to give for a week but I am seeing little to no change so I was looking at a chicken book that I have and it listed a couple of symptoms that this chick had for gapeworms except sneezing( I suspected crd/or infectious broncitis(sp?) but the chick doesnt have nasal discharge, watery or swollen eyes or diarrhea..I am at a total loss because other than the sneezing/head shaking and semi hard breathing this chick looks and acts like a normal healthy chick
