Help! Broken leg, slipped tendon or deformity?

[MarnieRose]

Hello, we just received some new Australian spotted ducklings from Metzer farms yesterday and one of our ducklings keeps her one foot up and hops around on the other. We tried to straighten it and it doesn’t want to straighten at the hock. I’m scared I’ll break her leg if I try to straighten it all the way. Any suggestions would be helpful on how to approach this!

I am not that familiar with ducklings, but I would call Metzer. It could be an injury from shipping, but you can human B complex vitamins at Walmart vitamin aisle for extra niacin. A 1/2 tablet can be crushed into some moistened feed or you can get the injectable liquid B complex from feed stores and give 1/4 ml daily. Make sure that she is not trampled. Here is a good buy:
