A buff brahma/EE chick hatched last night and its leg seems to be stuck straight up. Something is wrong with the joint. It's red and crusty and angular, though not bloody. The leg doesn't easily bend down, and when I try the poor little chick screams. It also hatched without all the yolk absorbed, but it didn't seem to be bothered. It popped out of the egg quickly and peeping up a storm, and it flung itself (and yolk) all over the bator in a matter of minutes after hatching. It's perfectly fine other than that leg.
The chick scoots around with the "knee" of the leg flat on the ground like it's the foot, and since the leg is stuck straight up it keeps poking itself in the eye with its toes.
All the other chicks are perfectly fine as far as I can tell, so I don't know if it's just a freak mishap or if it's something I did. I had humidity issues on hatch day...it got up to 90% then dropped back down. I still had 10 out of 11 fully developed eggs hatch though!
So what can I do for this leg? Anything? What would you do?
