Sebastapol Geese at Riverbend Farm
About the breed:
Sebastapol Geese are a medium sized goose, known for their long curling feathers.
Sebastopols have been called the 'pantomime goose' because of their fancy feathers. They have a curled feather mutation which gives the birds a fluffy appearance. The shaft of the longer feathers splits and the vane is fluted. So, the flight feathers are soft and trail to the ground. This would be a lethal mutation in the wild because the birds cannot fly. The birds illustrated are known as the curled feather variety.
Birds which are heterozygous for this mutation have curled feathers trailing only from the scapular (shoulder) and thigh coverts. The rest of the body feathers appear normal. The flight feathers are slightly fluted, and the tail feathers are also affected. This type is known as the smooth- breasted. A pair of these smooth-breasted birds birds will breed curly, smooth-breasted and also plain geese with no feather curl.
The best breeding combination is a mixture of the two types; such a pair will breed both types. It may also help counteract the tendency for angel wing in this breed. However, the weight and length of the flight feathers (in the curly type) often tends to pull the wing joint outwards.
The curled feather and the smooth breasted are both standardized in the UK. [The curly feather type is no longer called the frizzle because the gene behaves differently from the poultry frizzle gene]. In Germany it is just the smooth breasted that is standardized. In the USA, it is the curled feather variety.
Sebastopols are a light weight domestic goose weighing 4.5kg - 6.5kg.. Temperament varies depending on the strain, as does egg-laying capability. Some strains lay up to 40 eggs per year. Imported from the port of Sebastopol, they were figured and described in the Illustrated London News in 1860. Birds like these were reported from the countries surrounding the Black Sea, and the lower Danube - hence an alternative name: the Danubian goose.
How to Sex Sebastopols
Like all white European geese, white Sebastopol goslings are auto sexing, but this is not 100 percent reliable. The females are darker because they only have one dilution gene (which is sex-linked). The male has two dilution genes so he is paler. They also have the 'spot' gene which gives the 'saddleback' appearance in the fluff. In the feathers, dilution and spot together make European geese white. Note that 'white' in Asiatic geese is different - it is caused by a recessive white 'c' gene.
The favoured colour for Sebastopols was white: the curly feathers were probably used in Eastern Europe for bedding, and white would have been preferred. However, they were produced in Buff in the UK, and have been standardized in that colour. Crossing birds with Brecon or American Buffs to obtain the buff gene has also introduced grey (wild colour [not buff]). This would happen if it was not realized, in the initial cross, that the buff gene is sex-linked and the wrong breeding combination of male and female were used.
Also, the spot gene is revealed in cross-breeding if the dilution gene is bred out. So, Sebastopols are now also in buff back and grey back (saddleback, pied), and even whole grey. Blues have also been bred.
.In high rainfall areas they should be housed at night because the back feathers do not give such good protection as normal goose feathers. Also they must have clean paddling water to keep them in good condition, a dam is ideal.
