What does straight run mean in game bird buying?

In game bird buying, "straight run" refers to a group of birds that are sold without any sex differentiation, meaning the buyer receives both male and female birds without knowing the specific ratio of each. This term is commonly used in the poultry and game bird industries, particularly for species like pheasants or quail. Buyers choose straight run if they want a natural mix for breeding or hunting purposes, as it can be more economical than purchasing sexed birds.
