I lost a pullet yesterday. Today a yr old buff orpington appeared to have clear bubbles in one eye and I think I heard faint sneeze. All otherwise appear healthy, active, good appetites and those of laying age do seem to be laying, good weights aand glossy feathers I put Apple cider vinegar in water I try to keep my flock all natural. If I treat for respiratory illness: Is there an effective natural treatment? If I have to use an antibiotic what should I use and will the eggs be unsafe? If so, how long?
