I get them in the chute and use a soft, nylon rope around the hock. Wrap the rope around the top bar of the chute and pull up the leg. It's easier if you're pulling back instead of straight up. It's better with 2 people - one to hold the rope and adjust the tension accordingly - but doable by yourself as long as you tie the rope securely once you get the leg up/positioned. Plan B: just get her in the chute & do the best you can by sticking your fingers between the toes to check for foot rot, debris or an abscess (wear gloves - that smell doesn't wash off for a while!).
