Want this question answered?
if you mean eggs you buy in a store, then no, because these eggs were conceived by the bird without male fertilisation.
No, without fertilisation (mating) the egg will not develop further.
external fertilisation
fertilisation
Yes
The simple answer is Yes.
internal
Pandas are mammals and reproduce sexually by internal fertilisation.
Most fish reproduce using external fertilisation - the female lays her eggs, and the male then covers them with sperm, fertilising them. Some fish, however, use internal fertilisation. Sharks are an example. Males sharks have paired copulatory organs called claspers, one of which is inserted into the female's cloaca, depositing sperm inside her. In some species, eggs are then laid and will hatch after an incubation period, but in others the eggs are retained within the mother's body until the young are fully developed, when they are born alive.
Sea urchins generally have separate sexes and spawn seasonally every year. Eggs and sperm are usually released to the water column where fertilisation occurs.
The zebra top shell is in the family of Trochidae and most Trochidae reproduce by expelling sperm and eggs into the water for external fertilisation. In other species, the female lays a gelatinous egg-mass which is the early stages of larval development.
