One hatched 4 to go... but one is blotchy?

[cdmadaio]

I have successfully hatched one chick already and it looks as if another (1-2) will hatch today. It hasn't pipped yet (I think) but looks as if the air sack has been broken by the chick. This happened last night and I can hear it chirping. One of my bantam eggs though... I don't know what's the matter but it looks blotchy for lack of better words. There is one spot that is clear but is being invaded by dark lines and there are other blotches of clear throughout. Does anyone know what the problem is or if there's a problem?
