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
internal
The simple answer is Yes.
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.
Parthenogenesis is a type of asexual reproduction where organisms can reproduce without their eggs being fertilized by sperm. This is common in species such as reptiles, insects, and fish.
