I have two chickens that i have been treating with SMZ for chronic diarrhea. They have been treated for several days with no improvement but still have a few more days left. They are eating, drinking, and acting perfectly fine, however today one of them has started wheezing when she breathes. She is still acting fine but I have absolutely no idea what to do to help. I'm wondering if she might have aspirated some of the liquid antibiotic when I treated her last night since she fussed a little when I gave it to her.
