The Sebastopol is readily identified by its feathers. Long, soft-quilled, curling feathers drape elegantly from its wings, body and tail. This modification in plumage is an example of breeding for a specific trait. The white variety of the Sebastopol is best known. Both males and females have pure white feathers that contrast with their bright blue eyes and orange bills and feet. Juveniles often have traces of gray. There are also gray and buff color varieties.
Sebastopols are medium-sized geese, weighing 12 - 14 pounds when mature. They have large, rounded heads, prominent eyes, slightly arched necks, and keelless breasts. The plumage of the head and upper two-thirds of the neck is normal, while that of the breast and underbody is elongated and well-curled. The soft, fluffy feathers of the back, wings and tail have flexible shafts, are attractively spiraled, and in good specimens are so long that they nearly touch the ground. The curled feathers prevent flight making them easier to confine. Sebastopols produce 25-35 eggs annually. They have a quiet and pleasant disposition.
Whenever a domestic animal is selected for an unusual characteristic, great care must be taken to insure that vigor and fertility of breeding stock is not overlooked. Robust health and adequate size should be the foremost selection attributes. Secondarily, select for birds with well-curled breast feathers, flexible flight feathers, and back and tail plumes that are long, broad and spiraled. Avoid selecting breeding stock with crooked toes and slipped wings.
To keep Sebastopols looking good, clean water for swimming should be made available. While Sebastopols are hardy and are being raised successfully in cold climates, it is a good idea to provide more protection during wet, cold, and windy weather than normally afforded other breeds, as their loose fitting feathers do not provide as much warmth, nor do they shed water as well. Ganders can be mated with one to four geese. If low fertility is experienced, clipping the long plumes of the back and tail and the feathers around the vent is sometimes helpful. Sebastopols produce good quality meat for roasting.
