Hey, so i have a 4 month old duckling who was perfectly healthy until last month. Started off with a slight difficulty in breathing and now her condition's getting worse by the day. Most of the time she's panting, her wings always hang down, she eats very less, her eyes and nose are watery and she has severe diarrhea which doesn't seem to get any better. I've taken her to three different vets but the antibiotics and injections they've prescribed aren't helping so i've lost hope. Does anyone know what might be the problem?
