Your order will contain a mix of Black Copper, Blue Copper & Splash Copper chicks.  Basically, whatever hatches out is what we ship.  If you have a color preference, indicate it in the "notes" section during check out.  We will try our best to meet your color preferences.  We are not set up to fill only one color orders at this time.  All chicks are sold straight run.  Male and female Marans look identical at birth.
