Although I've never had eggs myself, I'd be inclined to say based on things I've read that you probably had a sudden spike or drop in temperature to cause those babies to come out like that. Your normal-looking babies may have been affected by it too, although not quite so conspicuously, and it might have something to do with the one not absorbing his yolk. All I can suggest is to put him in a little tuppaware container with some damp paper towels and wait. If he still doesn't absorb his yolk you can tie off the umbilical chord with a thread and cut it, then use a feeding syringe to to put some chicken yolk down his throat so he has some nutrition.

I'm sure somebody more experienced will chime in soon, too. I hope that he pulls through for you.
