    Egg drop syndrome

    Eggs produced by hens in a flock with EDS'76. One normal egg is present (center, back row). Affected eggs include pale and thin-shelled eggs and shell-less eggs. The contents of the egg at the bottom right have been lost, leaving a thick, collapsed shell membrane. Such membranes may be found admixed with droppings and can be easily overlooked.
