chickens do not, as many people think, go through "henopause". They keep laying till they die.
Meat hickens (except for capons) only live from 8 to 12 weeks depending on how fast they pack it on.
Being a long lived chicken that is loved and respected as another farmhand, is rewarded by tasty hardshelled embryos.
As daddy conehead would say
"I am experiencing morning hunger. I can consume mass quantities of chicken embryos"
