Do hens lay unfertilized eggs?

Hint: Reproduction is a natural process through which new organisms (offsprings) are produced from parent organisms. There are various ways of reproduction, some organisms give birth to young ones whereas some lay fertilized (egg + sperm) or unfertilized (no fusion of sperm) Eggs.

Complete answer:
1.A healthy adult hen will lay one egg every 24 to 27 hours most of the year, regardless of whether she has been exposed to a rooster. But the eggs will be infertile if the hen has not physically mated with a rooster.
2.If a hen has not mated with a rooster to receive his sperm, the hen's eggs are incapable of forming chicks.
3.Hens are the animal that keeps on laying eggs every day until they have achieved a Clutch which means 12 numbers of eggs. They don't need a male , rooster for them to fertilize them because they can actually lay eggs without getting them fertilized.
4.If we keep on taking away egg from them, they are going to produce egg regardless of the rooster’s sperm fertilizing them. They just want to achieve their clutch.
5.They keep on reproducing eggs until they are out of egg producing cells because they are also born with a limited number of eggs capacity like humans.
6.So it is concluded that, yes, hens do lay unfertilized eggs.

Note: Fertilized eggs will taste and look exactly like normal eggs as long as you are collecting them regularly. For an egg to develop into a chick, it needs to be kept in the perfect conditions. It will have to be 100 degrees along with 60% humidity for several hours. Even then, the development would be so minimum that it would almost be unnoticeable.
