Angel food cake takes 12 eggs. Of course that is only the whites, you have to figure out what to do with a dozen yolks. A very large batch of chocolate truffles will take care of them. And you can make eggnog with a dozen eggs.
I wish mine would learn to write. I do have a variety of breeds so I have a chance to know who laid what but I still have to catch them in the act and determine a difference between the eggs of girls that are the same breed.
I made an egg out of a scrap piece of cherry wood. Been in the nest box for a year and a half at least. It went missing a few months ago ... and showed back up in the nest a few days ago. I SWEAR I scrounged all through the shavings in the box when it disappeared. And yesterday a plastic egg that had been in another nest box for months was out in the barn alley.
