Just a thought:
I think I'd be more inclined to lay the egg down with the "blob" to one side. Hopefully, the chick would be heavy enough to still pull away due to gravity. I'd be afraid to put the blob up for fear that if it's the eye that's stuck a direct downward pressure would cause the chick to lose the eye, or at least the use of it, which it may well do, anyway.
If the eye is, in fact, stuck to the shell, I'm wondering if the chick's going to be able to get enough movement to pip. If it somehow managed a pip, I might go in; doubt seriously it'd be able to zip far enough, if at all, to hatch on its own.
Tough call
