We tried to leave a ceramic brown egg (marked with a pencil X) in each of four nest boxes as our hens came into laying age. We have 4 hens laying and they all lay in the same box every day. We started finding the fake egg from that box on the ground and one morning I caught one of our RIR hens pushing it out of the box. We pulled the fakes as it appears at least one of our girls can tell the difference!
