In order for a baby chick to grow inside an egg and eventually hatch, it must first be fertilized, like a human woman pregnant with a baby that eventually is born.
If an egg remains unfertilized, it can be used for human consumption.
Because they are not fertalized by a male chicken
No, firstly, they do not share the same habitat, secondly Armadillos normally eat bugs and insects not eggs or chicks.
Only fertilized eggs produce chicks and even then, only under certain conditions. The eggs you buy in the grocery store are not fertilized and can never be incubated. Most eggs sold in stores are not viable.
