As far as I know they don't know that the egg came first. That's been a question that has been debated for years and years without one real true answer.
Well, i don't think i can answer this...but i do know that the egg came first.& you may think; "Oh yeah, well then where'd the egg come from?"it clearly came from God.so there's your answer
If you believe in creationism, it was the turkey. If you believe in evolution, it was the egg.
The egg came first. Evolutionary changes over time resulted in the gradual transition of a bird species laying eggs with different traits, eventually leading to the chicken as we know it today.
I think the egg came first-not nessacerikly a chickens egg but an egg may have come first I think the chicken came first because, the chicken evolved from soemthing that wasnt a chicken and once it was a chicken it had an egg. but the egg the chickn came from had a chicken in... im confused This is one of those questions that has been debated for years. We may never know the answer...or perhaps we now do. In 2006 a geneticist, philosopher and chicken farmer say they have the answer. It was the egg. See link.
"Which came first, the chicken or the egg?" is a famous riddle that has no answer.
The egg.

my answer
the egg!
The hen's egg came first because other animals layed the egg!!!!
Maybe you aren't asking the right people! I for one can answer this question! The egg came first, as two birds (just say an ostrich and an emu?) could have mated and the emu could have laid an egg which made a chicken! The egg came before the chicken, now you know the answer too!
The chicken came first. Why? The chicken came first because the actual chicken evolved from an ancestor, the Archaeopteryx. Actually many birds evolved from this magnificent bird. Then the chicken lays the egg and so on.
