The Celadon Quail are a special variety of Coturnix Quail who carry a rare, recessive gene (the celadon gene) which causes their eggs to be a gorgeous blue color. Some are even speckled! However not all eggs are blue they run 80 percent true most of the time. All our quail are Non-GMO birds.Celadons make excellent pets as well as meat and egg producers. These quails are pretty hardy and generally calm, especially when they feel safe. They nestle in North America and weigh around 15 ounces when they reach full maturity
