Breeding Chart
The Blue gene in Blue Laced Red Wyandottes does not breed true. There are 3 colors of BLR Wyandottes: Black, Blue & Splash. The following chart may help explain how the different color genes work with different combinations. Here is also the link with graphics that might help you visualize it better.
If you mate:
Blue X Blue = 50% Blue, 25% Black, 25% Splash
Blue X Splash = 50% Blue, 50% Splash
Blue X Black = 50% Blue, 50% Black
Splash X Black = 100% Blue
Black X Black = 100% Black
Splash X Splash = 100% Splash
This is based on 100 chicks. When working with smaller numbers it is possible to have varying results.
