Hens, like females of all animals, are born with all of the eggs that they will ever produce already in their ovaries. Some hens that start laying later than others or that are slower layers can lay eggs for a longer period of time. However, whenever a hen has layed all of the eggs that she was born with, she will never lay another egg because she has no more to lay. It is just that simple. That is why they are called "spent hens." It has nothing to do with the amount of fat that they have or do not have.
Spent hens are only good for two things besides eating up all of your food... they can still be used as broody hens to incubate eggs from other chickens and to raise those chicks as her own. That is, IF she is a good broody hen and predisposed to want to lay on the eggs and raise the chicks. If not, then they are only good for the second thing... the crockpot!
