That's not common but it happens. Almost anything you could try to do will affect the others in the bator. Hopefully he'll have done that and then rest and he won't continue until the blood in the inner membrane is absorbed. But I had one kick completely free of the egg bleeding and with the yolk unabsorbed. I dusted the bleeding edges with some flour to stop the bleeding, and made a sleeping bag out of press-n-seal (like clingwrap and saranwrap only easier to use) sticky side out, with just his head out and told him to rest.
It's about all you can do. He actually did rest, recover, absorb the yolk and survive.
