Depending on your location?.....You might be able to contact a domestic livestock rescue group that will have a foster family that could rehab the Duckling?...My friend Tessa run a domestic all animal rescue and rehab....If your parents won't allow you to keep or care for the Duckling?....Try that....
and here's its leg. It's been eating and throwing itself in a container of water I have inside the box.. so it's okay but I'm worried about the leg, it hops around and can't get far so I'm afraid to give it back to its mother.
