Dear candidate!
according to the recent scientific reports the hen is the first one who came into existence as the protein that is found in the egg is made by hen. so scientist has proved that the hen came first not the egg because the protein that is used to make the egg is present in the hen.

Keep asking!
Regards!

Hen... Baby comes from mother this is the simple thing you should remember while asking this question. All the required essentials which a body needs can only be given by mom/ human body . So hen came first and then egg.

More simple thing to remember is, mom gives birth to child. Egg is an child and hen is mom.

Hello there,

This question remains in confusion all the time. And it is clear from the observations that all the chickens hatch from eggs and all chicken eggs are laid by chickens.

NPR's Robert Krulwich recently got to the bottom of the dilemma. His theory is given below.

Basically, many, many moons ago there was a chicken-like bird. It was genetically close to a chicken but wasn't a full-blown chicken yet. The video calls it a proto-chicken. So proto-hen laid an egg, and proto-rooster fertilized it. But when the genes from ma and pa almost-chicken fused, they combined in a new way, creating a mutation that accidentally made the baby different from its parents. Although it would take millennia for the difference to be noticed, that egg was different enough to become the official progenitor of a new species, now known as... the chicken! So in a nutshell (or an eggshell, if you like), two birds that weren't really chickens created a chicken egg, and hence, we have an answer: The egg came first, and then it hatched a chicken.

Hope this helps.
