In a strictly scientific answer, the egg came first. In evolution animals slowly change over hundreds of generations. Creatures that would eventually make the modern chicken, were not themselves chickens because they had not adapted the fetures of the modern chicken. So eventually there was a creature that was not a chicken that had a chicken as an offspring. The chicken offspring came from an egg, so the egg came first.
A Mares' offspring is called a "Foal".
Pigs offspring are called piglets.
In the film, Chicken Run, the chicken that knits is called Babs.
The offspring of different animals are known by different names- for example the oppsring of a Lion is called a cub, that of a cow is called a calf and so on.
