One of our female pekins has been unable to walk for 5 days now. Her legs move but her feet are all curled up and when she tries to move her legs just go under and behind her. I can't feel an egg stuck in her so I do not think she is egg bound. I put her in the tub (the ducks have not been swimming since the weather got colder) and her feet stayed curled but she could move around using her legs. She does not seem to be in pain but I am of course concerned. I've added an electrolyte/vitamin blend to their water but haven't seen a change in her. Any advice is appreciated.
