I always heard that if a chicken got a taste of a raw egg or whole shell, they would start eating their own eggs. I used to think it was crazy until I was feeding my grandma's flock. I accidentally dropped an egg. It brooke and all the hens rushed over and ate it before I could clean it up. The next day we got no eggs. The third day I found the hens cracking and breaking their eggs as soon as they were laid. It took almost two months to break their new habit.I'm curious as to your stance on egg yolks when I've read the opposite several times on here. Can you explain your position?
