ELI5: Is a chicken egg (like what you buy at the grocery store) a single cell, like a human egg?

My friend says that the eggs in the store are more than a single cell, but i thought that unless it was fertilized, an egg would remain a single cell.

If it IS a single cell, are the cell parts proportionate to the size of the cell, such that you could see the mitochondria with the naked eye?

The white and yellow parts of the egg are nutrients. They are used to feed the embryo if it gets fertilized. They are somewhat like a placenta. Eggs from the store are not fertilized, though, so they don't have the whole cell, but contain only the female part.
