  •   Last year in the Spring we found a chicken sized white egg buried in a patio flower pot, we nor any neighbours have chickens. This year we have found another partly buried in a garden border. We have a good variety of bird life but nothing large enough to lay an egg this size. We do have a kites nest in one tree but they rarely come to ground. Any ideas ?
