I've got 4 laying ducks, so about 3-4 eggs per day. I tried letting them hatch them, ground too cold, they wouldn't use a nest box . so on to this year. I'm going to try an incubator but do I put each day's 3 eggs in the "bator' every day? store them till I have 20 eggs? or do batches of 10? which I would still have to store. it is below freezing in the morning. their stall is warmer but certainly can't leave them w/ the hens.
