Hi I have a duckling that's 22 days old (breed unknown.) He's usually really active and runs around a lot. However i was cleaning his house today and I put him behind a baby hate when the gate fell onto the poor guy. I lifted it off of him quickly. The mesh part (possibly the wood part I didn't get a good look) hit him. He has no visible injuries but now he's just sitting down in one spot. He won't swim or run. I gave him his favourite treat, grapes, and he only ate some of the grape that I cut into eighths as opposed to his usual 2 grapes. I also noticed that his breathing seems to be labored. He breathes with 2 breaths and I just noticed now that he's making a weird snorting noise sort of like when you're trying to breathe with a stuffy nose or something. Does anyone know what's wrong and how to fix it?
