Thanks for all the responses. To be honest I got quiet depressed after reading the thread about the undisgestedyolk and really thought the little guy had it. To hear that he should be fine is a relief.

I did rinse him off once he was completely out of the egg and now have him in his own enclosure with water and hide box, although it looks like he prefers to between the paper towel to hide.

So far he is the only one to come completely out of the egg. One other guy has poked out but is still in his egg. The other egg that looks like it should hatch hasn't done anything yet.
