The Olandsk Dwarfs are actually an old breed from the island of Olandsk in Sweden. This is a landrace bird - developed naturally over the years by natural selection rather than breeding for a particular standars. Some have yellow legs, some have white, some have a straight comb, others more of a rose comb. The birds in the US were imported by Greenfire, and they say that they only brought in straight-combed birds. I would love to get my hands on a rose combed olandsk! At one time they were very rare, and may still be fairly rare in Sweden, but I think the numbers are increasing now that Greenfire introduced them to the US. I know that I have increased the world's population of Olandsk by about 30 chicks so far!
