My wife runs a business where among the things for sale are delicious pastries. Our secret is to use fresh, well cared for duck eggs in the batter. After about two weeks of wondering why I haven't gotten a single egg I decided to lay a trap. I took an egg from the hen house and placed it in the duck pen. After a couple minutes "Fifi" my sebastopol girl made a direct line for in, crunched it up and it was gone! I tried this a couple more times and she has actually made a habit out of searching the eggs out. We need our duck eggs and I love our geese, what can I do? Some helpful info: This started in the middle of winter which completely eliminates their ability to graze. They eat a poulin grain layer pellet staple with cracked corn, rabbit food pellets and any leftover kitchen veggies/fruits. They have grit available at all times. Please help me!
