I've been treating 3- fourish week old chicks for coccidiosis with sulfa/trimethoprim as instructed by doctor. Now they are sounding cruddy and sneezing. Doesn't that same med help with resp. Problems too? I have no clue what to do for chicks with this problem! Adults, yes but chicks, no. Can they have vet rx, moonlight mile respiratory drops...anything???? The vet is not in today. Please help!!
