The ducks have been laying since the spring....fairly well. 8-9 per day from 11. Since I switched from Blue Seal feed to TSC Dumor brand, I swear they are laying better. I have gotten an egg a day from each girl all week. I have 7 Khaki Campbells, 3 Pekins, and 1 Mallard. I figured the Mallard was done for the season two months ago, but she started up again this week. The most pretty green egg too. So glad that I finally have regular duck egg buyers.
