The breed has been known since the eighteenth century and is probably the result of crossing imported Spanish birds with local Bergische Kräher stock.[5] At the beginning of the nineteenth century the breed experienced competition from imported multi-purpose breeds such as the Minorca, and became almost extinct. A breed association, the Vereinigung der Züchter Bergischer Hühnerrassen, was established in 1916.[6]
Today the Bergische Schlotterkamm is an endangered breed. In 2001 it was an "endangered breed of the year" of the Gesellschaft zur Erhaltung alter und gefährdeter Haustierrassen;[5] it is listed in category I, "extremely endangered", on the Rote Liste of that organisation.[7]: 162 In 2013 the total population was around 250.[5]
A bantam version of the Schlotterkamm was created in the late twentieth century by cross-breeding bantam Bergische Kräher and Thüringer Barthuhn birds. It is found in one plumage colour only, Silver-laced Black, and is even rarer than the full-sized Schlotterkamm.[4][8]
Characteristics
The Schlotterkamm is a medium-sized dual-purpose chicken. The shape is long and somewhat rectangular. It has a single comb which flops from one side to the other; it is this that gave the breed its name. Four plumage colours – Cuckoo, Silver-laced Black, Gold-laced Black and Black – have been recognised since 1896.[4][9] The old Cuckoo variant had virtually disappeared by 1922,[9] and the white Schlotterkamm disappeared as the Leghorn breed became more popular.[6]
Use
The Schlotterkamm is a dual-purpose breed, reared both for eggs and for meat. Hens lay about 150 eggs per year; the eggs are white and weigh about 55 g.[3] The hens have little tendency to broodiness.[citation needed]
