Free: Contests & Raffles.
Find any of the porcelain eggs? They like to take things like clams and walnuts and drop them in the road, hoping to break them or have a car crush them.
We use golf balls which are way cheaper than ceramic eggs. Netting should help too.
I am thinking the hens have been laying but the Ravens have been getting the eggs. They are sneaky critters, never see them near the coop but the eggs just do not show up. Looks like they are watching when we go to the barn and hid up in the fir trees. Only cure is netting which goes up in a couple of days.
