Make a loop by threading some of the chain into the oval opening at either end. Slip the loop over the calf’s foot, above the joint. Then, make a half hitch by twisting the chain to create a loop, and wrap the loop around the area between the dew claw and hoof. Now you are pulling from two places, which makes it safer and more secure when pulling a calf. When you pull, it should bend the toe back slightly.
If you run out of room and need to reposition the chain, you can do so when the hock becomes visible. Undo the chain and reapply so that you slip the first loop above the hock. Make a half hitch by twisting the chain to create a loop and wrap the loop around the area above the calf’s foot just above the joint. Now you can pull again and you can also bring your calf jack up close.
