Usually, neither ducks nor geese are being bred or kept for the sole purpose of gathering down and feathers. For thousands of years, poultry has been part of human nutrition and has been kept mainly for this purpose. Down and feathers are a natural by-product of the poultrymeat industry or the poultry farming, respectively.
