Also, two days ago I picked up a very large egg, with shell, but with another egg without a shell wrapped around the outside. The girls had eaten the yolk, but the white and the membrane were still all there, the membrane wrapped tight round the shell. I peeled the membrane off and the egg was perfect. Would this have been an "egg within an egg" that was being produced? I've read about them, but not seen it happen.
Normal eggs in shells would be so nice...
