Has anyone else noticed issues with eggs stored in styrofoam vs cardboard? The last time I stored eggs for hatching in a foam carton, the temp fluctuated and some of them had porous spots on them. One or two smelled funny also. It seems like they breathe better with cardboard. I stored some this week in foam and I noticed the spots again on the eggs that were 3 days collected. Hmm. Am I crazy?
