Theory Chicken or egg first

• Eggs (in general): Preceded chickens by millions of years.
• Chicken eggs (containing chickens):The first true chicken hatched from an egg laid by a proto-chicken, so the egg came first in this specific context as well.”

“The egg came first, as eggs existed long before chickens, but the first chicken hatched from an egg laid by a bird that was almost a chicken, making the "chicken egg" (containing a chicken) precede the first adult chicken through a genetic mutation.
Evolutionarily, the egg, a reproductive structure, evolved hundreds of millions of years before the specific species Gallus gallus (chicken), which arose much more recently.

Evolutionary Explanation
Eggs Came First (Generally):
Hard-shelled amniotic eggs, allowing reproduction on land, appeared around 312 million years ago, long before birds, let alone chickens, existed.
The Proto-Chicken:
Chickens evolved from junglefowl.
A bird that was not quite a chicken (a "proto-chicken") mated with another proto-chicken.
The Genetic Mutation:
A genetic mutation occurred in the fertilized egg, resulting in the first animal that could be classified as a modern chicken.
The First Chicken:
This proto-chicken laid the first egg, which hatched into the first true chicken, meaning the egg containing the first chicken came before the chicken itself.
In Summary

• Eggs (in general): Preceded chickens by millions of years.
• Chicken eggs (containing chickens):The first true chicken hatched from an egg laid by a proto-chicken, so the egg came first in this specific context as well.”
