I had some ducks until the neighbor's complained. We bought them young and they started laying after about two months. After they started laying, for all but two days, we got one duck egg a day. We sold them a few weeks ago, but still have eggs in the fridge. We sold them for $200, along with a couple of partly opened bags of feed, a couple of containers, and their house. I gave $20 for each duck last year. Maybe we spent $20 a month on feed and fed them lettuce and greens. I dug up dandelions to feed them in early Spring. They also liked to eat whatever bugs were running around outside the house.
