Occasionally one of our hens will lay a soft shell egg or a really thin shelled egg, and she and the other chickens almost always eat them on the spot! Also if an egg accidentally gets cracked or crushed in the nest box, they will eat it. To my knowledge, they don't attempt to eat the normal eggs. They seem to somehow know that these are different and "OK" for them to eat. Anyone else have this experience? Also, our hens tend to drop the soft/thin shell eggs just anywhere - on the coop floor, in the grass outside, etc., while the normal eggs are almost always laid in the nest boxes. Fascinating!
