Baby shaking foot?

I had a chick that when it was born, its foot kept shaking. The mother broke the egg when it had just pipped but I know he was warm enough. He is fine now, I was just wondering why his foot was shaking. Here he is

That is strange! Have you tried the search feature to see if anyone else had this issue before?? They are very nice looking babies,...maybe he was happy to get out of the egg and was doing a little jig!

Good luck!
