How long were they in there? If it was all day, and If they were refridgerated before hand, then I would throw them out. I wouldn't risk it at all, not with my family. A dozen eggs or even a few dozen isn't worth the risk.
But you also gotta think about if they weren't refridgerated and it was only a couple hours, it could be just like an egg sitting in a nest box on a 95 degree day waiting to be collected....I guess it would depend on whether or not they were refridgerated.
