That one is easily solved.I thought it was chicken or the egg.
Nope the rooster did ....That one is easily solved.
Unfertilized chicken eggs are also called chicken eggs.
So they are called after the mother, and not after the chick.
So the bird that was in the evolutionary tree aaaaaaaaalmost a chicken laid and egg, which was an aaaaaaalmost-chicken-egg. From that egg hatched the first chicken.
So the chicken came first
