My 7 year old Buckeye had developed a honking respiratory sound a few weeks ago. First it was a couple times a week, but now it's all the time. Tried dabbing VetRX on her nostrils, etc and also on the rest of the flock. I tried giving her coconut oil in case something was stuck. I sprayed down (oregano spray) and cleaned the coop, which is well aerated. She's seems fine otherwise. I have a 2nd hen may be starting to honk sporadically. I have no meds on hand but will try to get what's needed. Ideas on how to proceed. No chicken vets here.
Have a couple others sneezing occasionally. The heat was horrible over the weekend. Did everything I could to try and keep them comfortable but short of bringing them in the air conditioned house, had no idea what else to do. Could the heat be the cause of this?
