Quality is rather impacted by things like the environment of beginning and the age of the bird, as opposed to its variety or species. Duck down is typically somewhat more affordable not on the grounds that it is a lower quality but rather in light of the fact that the worldwide stockpile of duck is a lot bigger than that of geese.
