Additional Details ------------------------------ Product description: We are glad to be offering our product on Amazon. Eggs shipped are collected fresh. We recommend at least 2 dozen purchase if 10-12 chicks are desired. Our Hatch Rate is 85% on average, but this should not be expected with Mail Order Eggs. Our Fertility rate is 95% or better with a 4 female to 1 male ratio. Coturnix Quail grow up to be on average 10-14 oz. Live weight. They also have the capability of laying eggs as young as 6-8 weeks. We try to package eggs as safely as possible, but USPS handles every package differently. If eggs are damaged, you may file a claim with USPS to recover the costs.
