I don't like being constrained to a week long acution. I like the 24 hour format. I know what my hens are laying right NOW, but a week from now, with hot weather, broodiness, what have you, things can change a lot in a week with the eggs, at least in my flock. PLEASE do not make every auction stretch out for a week, mandatory. Offer 24 hr, three day, week, ten days.
