God luck with the duck down there is a patch on their brood spot but many will pluck it them selves[ i think it depends on climate] most lose it when they molt after hatch and drakes don't have it at all. I gave up on duck down after I got geese. Dick feathers [small ones not flights] make firm pillows grandma used duck feathers for cores with a down outer wrap. THey smell and the smell is in the oil it takes alot of washing to remove the oil.
