please, which antibiotic did you use?Ours are pets too... we're the weirdos who take their ducks to the vet lol. The last time one of our ducks was sick with pneumonia we did use a vaporizer with Oxine AH (also from Majestic Waterfowl info) and it did help get her breathing better. We did it for 30 minutes twice a day in conjunction with oral antibiotics. It did help and after 30 days on antibiotics she's finally well again.
