I came across a toy wooden chicken some years ago that laid an egg (ping pong ball) when you pushed down on the body of the chicken. It stored about 4 or 5 eggs inside its body but I have never seen one since. I saw it lay the egg but didn't get to see the inside of the chicken so I don't know how the mechanics of it worked. I would like to make one of these but have not been able to find a plan for such a chicken and wondered if anyone had such a plan or drawing of how it works so I could make one.
