The chicken evolved in an environment at no further than 30° North. Most wild chickens live closer to the equator - both north and south of that line. Natural means 11 to 13 hour days, year-around.
Of course, they did not evolve indoors.
Selective breeding over the last few centuries and especially the last 100 years boosted the egg production of a wild chicken (less than 20 eggs) to well over 200 in the modern layer. They are now "built" for egg production but still "geared" to their natural environment.
