What causes a chicken to lay eggs with only a membrane no shell? She has done this at least twice that I know of and it is usually at night when she is on the roost. And of course it breaks open when it hits the ground. THe chickens have access to oyster shells and also crunched up egg shells on the side. I don't have that problem with the other chickens.
