Question

how can you obtain fertilised and un fertilised eggs?​

Answer 1

Answer:

For the eggs to be fertilized, the hen and rooster must mate first, and this process must occur prior to the formation of the egg. Thus, if the hen has mated and she lays an egg, then that egg is fertilized. If the hen has not mated and she lays an egg, then that egg is unfertilized.

Answer 2

Answer:

Unfertilized eggs are obtained when hen is laying eggs in the absence of rooster. These are available in local stores. Fertilized eggs are obtained when hen mate with rooster to produce egg.
