If it's a fertilized egg but hasn't been incubated, it's just a few cells. It's not really any more of a living thing than, say, a bacterium. It's technically alive but isn't capable of suffering, and definitely isn't a chick. Even if it has been sat on for 24 hours and is technically an embryo, it's still not alive. It's just a bunch of cells without any organs or anything.
During a menstrual cycle, several eggs are shed. If the person owning that uterus has, we'll say mated, there could be fertilized eggs there that didn't properly implant and are therefore being shed instead of growing into a fetus. Nobody reasonable holds a funeral over tampons. Same idea.
Just because an egg could be incubated to grow a chick doesn't mean a chick is in there now. You have nothing to worry about.
