I've got 12 mallards that ate laying eggs but they are eating about half that they lay,any tips on how to get them to stop pecking them open? Also how does everyone store the eggs until its time to set them in incubator. I've got 2 quality incubators with turners and have good temps/ humidity but still low hatch rates,so I'm thinking its gota be before I set them is where the problem is. No wonder ducks are expensive,because they are kinda a pain in the azz. Any tips appreciated.
