There are also seasons in the tropics, where the off season is a dry
season. But those of us from Europe had ancestors that left the tropics
some 500,000 years ago.

Chickens are raised in hen houses in which day length is controlled by
artificial lighting - it is day length which stimulates changes in hormonal
profiles which induce ovulation (i.e. egg laying).
