Well, crap. I WANT mine to lay a shell-less egg with membrane in tact, so I can incubate it and see what happens. But my darn girls just don't want to participate with this!
Frankly, I don't know why you would bother. When selecting eggs for incubation it is best to select the best eggs. To start the process with an inferior egg seems ludicrous to me. It has been done before!
