Very white half egg shell, approx. 3cm diameter, found at the base of a tall leylandii hedge, complete with no cracks, with membrane attached to all parts of the remaining shell and a jagged broken edge. (There was only some hedge debris inside) Surely it's too late in the season for hatching eggs, and I walk past the hedge nearly every day and hadn't seen it before. It was very conspicuous because of its brilliant whiteness. What bird is it from? Could it have been preserved in the hedge since spring in such an unbroken state and been blown down in recent very windy conditions?
