I have read that a hen will lay about 20 dozen (240) eggs in the first year and probably no more than 1000 in her lifetime. I have read that chicken's average life span is 8 years. I am wondering: can you stretch out egg production in a hen by not adding extra light in winter and letting her go broody every once in a while? Or does adding light in winter only ADD more eggs produced in a chicken's lifetime? After the first two years, what can I expect from my pullets? Outside of eating them and pets, is there a use for them? Also, when is the best time to let them brood out chicks? Is the quality of the chicks lower if the hen is past two years old? Or if the hen is less than a year old? Finally: will a pullet go broody if she is no longer producing eggs?
