2 of my 6 ducks are finally laying! However, they are burying their eggs. And while it's not a major inconvenience, it does take time, and I've broken 2 trying to gently rake through the coop shavings to find them. I could do it with my hands, but it's an 8x8 coop, so not small, and they move them around every day. And, duck poop Is this just life with ducks, or is there a way to keep them from burying them?
