Concerning Pen-Raised Quail
Stocking pen-raised bobwhites to increase breeding populations of quail is generally considered unjustified by most biologists due to low survival rates, and has been implicated in the decline of native quail populations because of the potential for disease introduction, food and/or mate competition, displacement of wild quail, increasing wild quail mortality, and dilution of the native gene pool or reduction of brood rearing ability through cross-breeding.
