If little bunnies have the Californian markings but the color points are blue, are those points going to darken up? They are 10 weeks old. The bunnies aren't purebred. Sire is purebred Californian, dams are 1/2 Californian and are white with black spots. Litters contain black, a taupe color (silvery chocolate), white w black spots and a lot of Siamese marked bunnies with frosty blue points.
