I would say they weigh around 7-8 lbs each. The male has an attitude, like a lot of small dogs have. He will show off and act tough, but he backs down if you blink at him! The girls are very sweet. They can fly, and I haven't clipped their wings because I get such a kick out of their flying out of the barn when released. That's all they attempt because they are so bonded to the Sebs who don't fly. They are sex-linked like Pilgrims (which are prob in their genetic background). The males are white or are splashes and the females are gray and white. I got mine as adults last Feb., and they became tame fairly quickly when they figured out I was their provider of food and treats! I hope to have a few goslings in the Spring.
