The store bought eggs that have potential to hatch are all labeled "fertile eggs". No other grocery store eggs are fertile, therefore will not hatch.
I set 11 eggs last month from my nearby co-op grocery store, Rock Island Brown fertile eggs. I got 6 lively yellow chicks out of it. 2 were clear (un fertile), 3 developed to different stages but didn't hatch.
You can eat fertile eggs, they don't change until they have been warmed 95 F or higher for 24 hours. Fertile eggs are only a 1/2 cell different from unfertile eggs.
