Here you go, post #4:Hey guys, I recently purchased a light Sussex pullet. I noticed yesterday she was gasping and wheezing. I have her isolated from the others in a totally different location. She is on duramycin ( in water ), probiotic food powder, ACV in her water, and also vetrx on her nose, down her throat and under her wings. I looked for injectable Tylan and my TSC didn't have it. She is acting TOTALLY normal minus the gasping and wheezing. She is eating and I'm pretty sure she is drinking. I noticed that she has HORRIBLE. Breath and it smells like the sour crop fluid, but I know it's not sour crop. I also looked down her throat and she has a large white, almost pus like build up in her throat. It's very odd. I've never encountered anything like this before. I have pics, but they are not that clear and you can barely see it. Any help would be wonderful!
