I plan to hatch some out this fall to refresh my breeders. But I'll keep these until they aren't laying well. I only get 6-8 eggs from my 9 jumbo brown hens a day anyway, and the oldest ones are right now about 7 months old. But I think that's how I'll do it, hatch in the fall (late as possible) for the next season's breeders. Haven't decided yet if I'm going to keep a light on them for over the winter laying.
