sick? or what

[poultry guy]

my female mallard duck is poofing up and half weezing and half qaucking also she's qaucking very high pitched she never quacks like she normally does i'm worried she been doing these things for the past 3 weeks also in any case would a male duck sit on the nest

Is she still wheezing?

She sounds like she is in respiratory distress. You've allowed her to go on like that for 3 weeks???

I've never heard of drakes sitting on a nest.
