if you are not sure of their viability post a good pic of them and I (we) should be able to tell you if they have collapsed. I have pics somewhere but cannot find them
As feenie said, it is helpful to keep them in some humidity and warmth. I hatch mine out in a petri dish that sits on top of the strip light. The bottom heat is perfect.
Did you say you have them in the sun? NOT a good idea - you can fry them. Warmth but not direct sun.
