I have 7 hens that are about a year old, maybe just over. Yesterday I noticed one that coughed once or twice while I was out collecting eggs but didn't think anything of it. Today there are at least 4 that are coughing, one that has wheezing/rattling sound and I Think I've seen them sneeze once or twice?? One in particular is holding her head out to breathe better, They are still eating but I guess are a little less energetic today than normal. Have been reading about gapeworm and tried to cotton swab one's throat but didn't see much, but also didn't want to put it way far down in case of injury. Do you think this is a respiratory issue? Gapeworm? It's really cold here in the middle of winter so....who know? I need to run out and get medication ASAP i just don't know what my best option is... Please help I hate my girls being sick!
