Hi guys. I need help. My 3 week old duck has a really swollen upper leg. I don’t see any bones protruding. What can I do.

Could you upload some pictures?
What type of bedding are you using?

Did the duckling accidentally get stepped on or dropped or fall off of something?

I highly doubt it. The are in a tub with pine shredding.

Pictures would help. Are you feeding starter/grower? are you adding niacin if yes what form?
