Duckling with curled feet

[Brittybee]

So my boyfriend and I got four ducks about a month ago (yay!). I have always kept an eye on the runt, but a month later and the others are 3x the size of her. I was sitting out with them the other day and I noticed her feet are curled in, somehow she has learned to walk on her knees.. elbows? I have read about taping the feet with cardboard or an old credit card, but my question is.. is it too late to try to save her feet?

Have you been giving them Brewers yeast? I had a duckling the same way about a month ago. The problem with her was when she learned to walk on her knees, it stop the blood flow to her feet. I could not straighten her legs and her feet were cold as ice, when I choice to put her down. Yes I you cut cardboard or an old credit card and tape them to the webbing it will straighten her feet out. Unless it is already to late. Not to sure on how long is to long. I hope this helps.
