We found another shell-less egg in a nest box. My youngest was helping so I held the fragile egg and a normal egg up to the light, and she took a picture, because it was neat to see the transparency of the odd egg. I say the egg was shell-less, but it did have a very thin layer of hardened material, then a thick membrane. Touching it caused a dent, but then gently rolling it in my fingers didn’t break the egg and made it look more like a fluid-filled latex balloon. I weighed it and recorded it in the book, then we gave it to the dogs. Griffin was quite surprised when he picked up the egg and left most of it behind! Missy didn’t mind cleaning up.
