In starting out your breeding program for the colors it is essential to choose the right genetics that dominate the characteristics. Plus along with this comes health, well balance, sound structured and temperaments. When we are breeding for these colors we should all strive to preserve the quality of the breed.
Wishing you the best in your breeding program!!!
