Texas farmer Gary noticed a strange phenomenon with one of his chickens from the farm. His seven-month-old chicken named Gertrude started laying very large eggs with another egg inside them. Despite the strange occurrence, Gertrude does not seem to have been harmed and the egg yolks have a normal taste.

This phenomenon, however unusual, isn’t all that rare really. A housewife got the shock of her life when she cracked open a huge egg to find a smaller egg inside - perfectly intact. Maria Glória de Souza collected the gigantic egg from the chicken coop in the backyard of her house in Catalao, central Brazil, after it was laid by one of her hens. The ginormous offering was triple the size of a normal egg, weighing in at 6.5 ounces. The phenomenon is called a counter-peristalsis contraction and occurs while the hen is in the process of forming an egg, where a second yolk is being released before the first egg forms completely.

This counter-peristalsis contraction, resulting from the premature release of a second egg cell into the oviduct, causes the first egg in the eggshell gland to reverse its course and be pushed back up to the top of the oviduct and then added to the egg cell that was just released into the oviduct.
