Looks like you got some interesting colors in this litter. The mother is a chestnut, right? I assume the white buck is the father? It looks like he has dark eyes, which would make him a frosted (also called an ermine). That would also explain a lot of why you got such a range of colors. I see chinchillas, and either a silver marten or an otter (that's the mostly black one. If the little triangle of lighter fur behind the ears is white, it's a silver marten. Otherwise it's an otter).
Looks like your new litter is going to be an assortment, as well.
