I have one Muscovy that started to lay 9 days ago. I've been collecting the eggs and bringing them in before they freeze. I have about 8 eggs. They are just sitting at room temp. It's cold here in WI. Outside it's well below freezing, but the coop has been fluctuating above and below freezing since it's somewhat insulated. How do I get her to sit on the eggs once I've collected enough? Just lay them all down in a nest with a heat pad until she lays on them then remove the pad? Is it just too early in the season?
