Double yolk chicken egg strange odd and rare
A double-yolked egg occurs when two egg yolks are released into a hen's oviduct too close together and end up encased within the same shell. Generally about an hour after an egg is laid, the next yolk is released, but due to hormonal change/imbalance, an overstimulated ovary sometimes misfires and releases the yolk too early. The shell forms around both yolks and results in a single egg.
