Question

what came first Egg or hen? how

Answer 1

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

heya,

I think that hen came first..

they might have been germinated by the same process as formed bacteria...

hope it is helpful
