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.
