Lately, I have been noticing that my Ancona drake has been making strange noises! He cranes his neck and makes a funny sounding quack and then makes a high pitched sound, as though he's burping!? I called the vet about a week ago, and I told them what was going on. The vet told me it sounded like he had an infection, and prescribed some antibiotics to give to my drake and my hen, (just in case she had a infection too). I squirted, I think it was 2cc of antibiotics in each duck's mouth once a day, for three days. It seemed to help for a few days, then I noticed him making weird noises again! He was making these strange sounds a lot yesterday. Does this sound normal, or is it something else? This is a picture of my hen and my drake.
