(NOTE: no double yolk egg is currently in the possession of the crazy person asking this question - question is purely theoretical in nature. thank you) so, do double yolked eggs every develop? is it possible to hatch "twins" out of one egg or do the chickies get to big and perish before development is complete? it seems like it would in most cases be "incompatable with life" but . . . nature is strange. anyone have any "i hatched a double-yolked egg" stories?
