Double Yolk Eggs

Yes, there's nothing like a farm fresh egg.  Especially if it's a double yolk egg!

Double-yolk eggs occur when ovulation occurs too rapidly, or when one yolk becomes joined with another yolk. These eggs may be the result of a young hen's reproductive cycle not yet being synchronized.[6] Some hybrid breeds of hens also produce double-yolk eggs by default. Such eggs are produced in India. Eastern states known for that are West Bengal and Andhra Pradesh.
Some hens will rarely lay double-yolked eggs as the result of unsynchronized production cycles. Although heredity causes some hens to have a higher propensity to lay double-yolked eggs, these occur more frequently as occasional abnormalities in young hens beginning to lay.[citation needed] Usually, a double-yolked egg will be longer and thinner than an ordinary single-yolk egg. Double-yolked eggs usually only lead to observed successful hatchlings under human intervention, as the chickens interfere with each other's hatching process and die.[7]
Rarely, higher-order yolks occur, although heavier poultry breeds such as the buff Orpington have been known to lay triple yolk eggs in their lifetime.
