Or you can find the same thing at any drug store in their first aid area (that is what I used) - it's just a non-adhesive fabric like, stretchy tape, that sticks to itself. You might need a helper, but stand your duck up and pull her legs into proper position. Use the tape to go around one leg, then wrap to the other leg, around that, and back again, so that when she walks or does anything her legs are forced to remain in that position. Do that and keep the vitamin B complex going generously and in a couple of weeks I think you'll be happy with the results. I was so worried that we would have to carry my duck around for the rest of her life, but this was a game-changer for us. Good luck!
