Hello! So we have a baby Mallard that appears to have a broken leg. It's swollen at the base of the leg and he doesn't put any weight on it at all. We just got 6 ducks and saw this one was struggling so we separated him and a friend so he wouldn't be lonely. But my main worry is he's way smaller than his friends which we got at the same time at the same age! They're maybe 1-3 weeks old. He is eating and drinking perfectly, and getting around despite his injury. But I was wondering if I should splint him or if I should just let him heal as he naturally would. Also should I be worried that he is smaller than his friends! Thanks so much for any help at all, I'm new to the duck owner life and my family has more of a farmers mindset on if they get injured they will just die and there is no point in fighting for their little lives so besides my husband I'm alone in trying to rehabilitate him.
