Sounds a little like spraddle leg. You can make a little hobble out of vet wrap to fix it. It only has to stay on 24 hours and the legs should straighten up and not kick out to the sides. I had one like that this hatch and 24 hours later I took off the hobble and can't even tell which one it...
My new babies (Ameraucana)! Hatched yesterday. Out of 7 set, 2 were duds. 5 still good at lock-down. 4 hatched, one died in its shell - malposition. Not terrible for eggs shipped from GA to CA! :-)
