An old thread but great topic. My sister started most of her chicks at the same time, and then 5-6 years later ended up with only one regularly-laying hen because she was the youngest. I wanted to avoid that, so I plan on getting a few new chicks every year (plus, my kids are 7 and 9; how great is it to get to play with chicks every spring as a kid?! OK, it's great as a grown up too!). That way, my flock is never comprised of chickens all the same age.
(Apparently you should do this with car-buying as well. You don't want to wind up having both people needing a new car at the same time; it's much easier if someone always has a car about 5 years older than the other person's car, then repairs and replacement costs rarely line up in the same year).
My sister wound up with a chicken with cancer who died this year and a blind chicken that did fine for 6+ years until she disappeared this spring, so she never did have to cull the old birds. Then again, she only has 1 layer and a few chicks right now, so she's not getting many eggs. I hope that mine die of natural causes as they get older, but we are not opposed to eating them if they are not laying and are not favorites (some I just know we will keep until the day they die, no matter what).
