I use rubber eggs to try to persuade my wayward girls to lay in the coop. It hasn't worked so well, so very day has been an Easter egg hunt day for me. So....my girls get used to laying in a few spots in the hedge etc. I place a couple of rubber eggs there to persuade them to continue to use the same site. What happened? Well, I saw a crow with one in his talons, and found he had removed the rubber eggs from the coop. And the ones in the hedge......rat bitten. I am wishing severe indigestion on them all right now.
