My golden buff hen was having mites problem before, after treating him with a spray advised by a vet he was doing perfectly okay. He is active , runs alot , but yesterday i saw whitish discharge from his left eye. Cleaned it up but today it was there again. Had to use a tissue to clean up the eye. Seemed whitish but on tissue the liquid color is somehow brownish. He is opening his beak sometimes alot like hes gasping for air ...nseemed normal to me as summer is almost here now. Any help will be appreciated.
