No. the female releases unfertilised eggs that are then fertilised by the male.
The eggs in stores are unfertilised because they have not been kept warm where as a normal egg would have been.
If it is chicken eggs you are talking about you will find that the eggs that are for sale at the market are not fertilised. If you want fertilised eggs you will have to get them from some one or a farmer that supplies eggs for chicks.You can purchase hatching eggs FERTILIZED from many hatcherys across the usa
Under normal conditions the male will protect the good fertilised eggs and eat the unfertilised or bad eggs.
There is no difference. All eggs that go to your store are fertilized anyway, there's no way that a hen could or would lay an unfertilized egg.

The eggs will go white (fungussy) within 36 hours if they are not fertilised. There are always some unfertilised (white) eggs. There will be tiny fry visible after around 4-5 days after spawning.
Unfertilised, all large companies keep their laying hens separate from their breeding hens and cockerels.
I have never heard of any species that can do both. One would assume that a creature would either lay internally fertilised, (or unfertilised) ova in the form of eggs, or produce live young. For a creature to do both would be most unusual.
