Is this a respiratory infection?

[Breannemoreno]

Hi, My Indian Runner duck Tulip is walking around wheezing, making little gasps. She is otherwise fine and eating/ drinking and hanging out as normal. We don't live near a farm vet. Is there anywhere I can get her antibiotics if this is an upper respiratory infection? I'm not sure what this is. Thank you!

I'm pretty sure they sell them at Tractor Supply.
