I normally hatch just polish eggs and I have those colors figured out. But my splash silkie went broody so I let her sit on 5 eggs. I have her and one other hen in a separate pen from the polish. The roo is a black silkie. So far she has hatched out a white, 1 light and 1 dark gray colored chick......and a partridge chick. Where to heck did the partridge color come from?
