I had so many respiratory problems. Hard to hit it right on the head. No vets around here want to help with poultry. Sadly had to cull a few. After hours and hours of researching. Found info on Oxine, I'd never heard of it. Took my chances, ordered it, mixed it accordingly and misted it the remaining flock's faces. Some that I left were still sneezing, but no more! This stuff rocks!! I recommend this to anyone whos having respiratory troubles. It covers ALL. Google it! I lost alot, but I finally have a nice healthy flock again!!!!
