Duckling with a dislocated ankle how to fix?

[Unpun]

Hi first time Hatcher and just to be clear (I had people yell at me for it) yes I "assisted" a hatch but I did not force hatch it. It was in the egg for three days and began peeping softly I took a flashlight to look for blood vessels I didn't see any. I took tweezers and helped take off the hard shell so he could push himself out. when I realized he couldn't do it and began peeping softly again I took off carefully the membrane without a bleed out and he used his good leg to get himself out. he was halfway in the egg still so I put him in the incubator and I went to bed the next morning he was only using one leg. So to cut this story shorter here's a pic. I helped others hatched and they are fine so is this normal can I fix it? I'm really scared cuz I don't want this to be serious.

I think it's a dislocated leg I don't know how to fix it I'm really scared that I'll mess up and break it or it will loose it's leg forever. I looked up the anatomy skeletal system (not a vet but am in school for ultrasound tech) I'm afraid he's too small or I'm not going to do this right. If I'm wrong please tell me.

I am going to suggest treating your duckling with human vitamin B complex 1/4 tablet daily crushed and fed with a little water. If you can I would also post on the duck forum here:

Here are some threads and a splinting article:

Okay just because people might be looking for answers. I took it to a small animal Dr and he said it's a birth defect at least I know it's nothing serious. He has a hard time eating and drinking without me helping him and he only wants to sleep in my hand am I taking care of him correctly?
