I'm getting no eggs at all. I have six ducks: two 2 year old ducks, two 5-month old ducks, and two 5 month old drakes. I've never had an egg from the young ducks, and the older ones have stopped laying as well. Food? I feed them all-purpose and layer feed (1/2 and 1/2) and kitchen scraps. Crowded? The duckhouse is 4' by 4' and they're in it from sundown to sunup. They have a yard 40' by 30' during the day, with two kiddie pools. No privacy? The nestbox is 2' wide, leaving a 1' space on either side which is not covered. For a while, one of the older ducks laid her eggs in both of those spaces. My chickens have slowed way down, so maybe it's the dark and the rain (Puget Sound area), but my older ducks laid through the winter last year. So, I think I must be doing something wrong. Help?
