It is interesting that the buff color is not common in wild waterfowl. Most other domestic and wild geese have combinations of white, gray and black coloring.
The Buff goose was developed for commercial meat production and the claim is that their feathers are easier to remove than white, gray or black feathers as they are less strongly rooted. The remaining pin feathers are so light in color, the carcass is as clean appearing as a white goose. Buffs are a calm, friendly breed and beautiful to watch - especially in a reddish orange sunset. Several years ago we sold some Buff and Tufted Buff goslings to Andrea Heesters of the Netherlands.
