Sorry but probably none of them... All U.S. commercial egg companies have hens that never see a rooster their entire life. If you are somewhere other than the U.S. then I don't know how they handle egg processing.
Your only chance is with organic eggs or local farmer eggs which have a rooster in the flock. Read on the egg carton where the eggs come from and look up the farm and call and ask if they keep a rooster with thier hens. If so then you may have a small chance of finding a viable egg. Or ask them for eggs, and skip the grocer all together.
If the eggs are washed, which they should be, they are less likely to hatch. If they are refridgerated, which they should be, they are less likely to hatch. If they are transported, which they have to be, they are less likely to hatch. The more they are handled and moved around and the longer they wait from the day laid the less likely they will hatch.
So, all said: if there is a rooster and they are freshly delivered to the grocer (like that day), and you have a good incubator then you may get a few to hatch. Do your homework first otherwise you are waisting your time.
Good luck
