Question

who came first on to the Earth hen or egg​

Answer 1

Answer:

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.

Answer 2

Answer:

The egg

Explanation:

Chickens would have evolved from a previously existing animal such as a dinosaur. Dinosuars lay eggs and chickens hatch from eggs so from thousands of generations of mutation, the chicken would have been formed. However, due to the chicken hatching from an egg, the chicken egg would have come first.
