Sizes and lengths of each feather differs from the photos of course, but each feather is from an adult male at Owl Farm. Each feather is sent in a protective tube and each order of feathers comes with a certificate of authenticity. Because peacocks only drop their train feathers once a year, there is a limited supply each year. Feathers are sterilized, but no chemicals that can dull the color are used. They are shipped and insured, but, obviously cannot be replaced because of the fact that each feather is unique. Male peafowl are called "peacocks" and females are called "peahens" and only males have train feathers. If you would like female brown feathers, please contact us at info@gonzonation.org. Thank you.
