I have a hen that has always seemed to be more Sneezy than the others but every time I listen to her lungs she never sounds congested or shows any signs of congestion by her nostrils. Today I noticed she's sneezing more than usual. I had 2 chickens die this past week from what appears to be coccidiosis which I know is high in my soil so I am treating entire flock with corid. I also found mites in the coop which appeared to be a moderate outbreak as I didn't find any on the chickens or large clusters. All chickens have been treated and coop cleaned with elector psp. Should I also treat everyone with antibiotics or separate and treat this hen? I also have dewormers if it could be that. She's acting normal otherwise and is a healthy weight and appearance. Any advice appreciated! I'll try to upload a video but my phone saves it in an unsupported format.
