I have a buff duckling that is 6 weeks old and has lad and growth issues. She is about a 5th of the size of the other two and has hardly any feathers growing in, but the thing I am most concerned with is her legs. She walks but her legs are almost crossed and she trips over herself, and when she stands one leg is crossed over the other. I assumed it was a niacin deficiency so I have been supplementing 125mg of niacin per gallon of water for about 3 weeks now. She was shaking before and now that has stopped but the crossed legs have gotten worse. What can I do to cure this problem? I'm thinking if I could wrap her hips with a bandage it could force her legs out. Has anyone else experienced this? Thanks for your help.
