Is this both legs or just the one? Can she stand and walk at all? when did this start?
It looks pretty bad but let's not give up hope until you've tried the liquid b complex. I'd also make her a shoe if she isn't laying her foot flat. You can take a piece of plastic from a cool whip container or something similar. Lay her foot on it and draw an outline of her foot then cut to the shape wrap in some kind of tape to cover the sharp edges. Then lay her foot flat out in a normal position and use a tape that won't stick to her skin Vet wrap works great. Go up above her ankle so she can't get it off. and make sure not to wrap too tight the circulation is cut off.
@Cori M has a really good video of how she helped her Pekin.
