About two weeks ago one of my Pekin ducks stopped walking, and eating. She's about 9 weeks old, and hasn't had any issues prior. We checked for bumblefoot and she had maybe two tiny spots that we took care of right away. Well she's still not walking and her legs are swollen. So then we started spraying, and wrapping them daily and we got her own little pool so she could bathe. Since she wasn't with the other ducks out wandering, I figured she was getting lonely so I started to put the 8 week old chicks in her pen and it's been such a transition. She's eating, drinking and getting her spunk back, but she is still not walking what could this be? I've heard about Niacin deficiencies but wouldn't she be showing symptoms of that from hatch? Since wrapping, her swelling has been going down.
