This item is 10 secondary buff feathers from a Buff Orpington rooster, raised here on our farm. They are not iridescent, although some are very shiny. They are a nice medium size, between 3 and 5 inches long and in very good condition. Secondaries are some of my favorite feathers because they have a perfect "feather" shape to them, plus shine and a manageable size. The birds do free range and have quite a lot of terrain to cover and things to get into, but these ones are in incredibly perfect shape. I think the Orpingtons tend to be less frisky than some of the other breeds we raise. Our birds are hatched under mother hens and raised on grass and bugs from day one. We utilize as much of the bird as possible, striving for the most sustainable system possible. This means breeding our own stock, using minimal inputs of feed or electricity, and also processing the roosters for meat. We are really proud of the feathers we sell, I think they are the most ethical and sustainable feathers available.
