I have 10 6 week old chicks in a pen. 2 have gotten sick, one walks on her hocks, the other has one paralyzed leg. Both breath and then also gasp every 5 seconds or so. The rest look fine. The only thing that fits is Aspergillosis. I'm treating with vitamins and electrolytes for now. Is there any hope that they will get better and live? Or will they die? The only source I can think of is maybe some feed got on the ground around their bowl and got wet, and 2 ate it. Would that make sense? I feel real bad, it's never happened to me before. Any hope?
