Welcome to Just Answer. We are an online advice service. You are through to Dr Coles. I am a UK based vet. I am sorry to hear you are having problems with your duck. It sounds like she is having respiratory issues. Respiratory issues in ducks can be caused by several different things, such as parasites (gapeworm), infections such as chlamydia, mycoplasma etc. Do you know what type of antibiotics they were on? Some infections do not respond to certain types of antibiotics especially chlamydia and mycoplasma, these are usually best treated with doxycyline. I would advise taking your duck to the vet again ASAP and they may take swabs of the mouth/nostrils to try and diagnose what is causing the infection.
