Hi ...I have a 3 year old Buff Orpington chicken that has developed a "cough"....this cough comes and goes....over the last several months.
She seems perfectly fine....eating, drinking, active and laying eggs.
I have 4 other chickens none have come down with the "cough".
I've tried adding ACV to the drinking water, as well as Vet Rx...nothing seems to help her.
Right now her "cough" is the worst its been.
She doesn't seem to be suffering, just coughing and shaking her head. No discharge anywhere.
I'm at a loss. Suggestions?
