Some people make a little shoe out of cardboard or plastic and tape the foot to it in the correct position to get it to hold shape. You have to do it young if you want to correct it before the bones set.
So glad you got a few to hatch, Mary. What'd you get? Looks like 4 Orps, 2 Sebrights, and 1 itty bitty Silkie? The foot thing, you could make the "shoe" like Jody suggested, and see if that works. Congrats, by the way!
