This super nutritious air-dried treat is made by wrapping lean beef meat over a quail egg yoke. Each ball contains one whole quail egg yolk, making it resembles our human mooncake when you cut it open. Quail egg is a complete source of nutrition, even higher than that of chicken eggs. Due to the fact that quail's body temperature being higher than chicken, it does not carry Salmonella. The air-drying time of this treat is rather long, we can only made to order, normal delivery is around 2 days after the order is placed.
