Looks like a Svart Hona to me. Just has had frostbite to the comb. The mulberry facial coloring is common on the males of fibromelanistic breeds. The goal, colorwise, is to breed for the darkest and closest to black. Being a land race breed, there is much work to do.
I'll look at mine now that they are older. Only thing I can think of for the skin coloring is that they have not come from strict breeding. Outwardly they appear Svart Hona.
