An EIDER is a type of duck, and DOWN are the small fluffy feathers on a duck or other large bird.

Because they don't mat, they trap a lot of air providing good insulation. They are very warm.

That depends on the type of feather. Feathers vary in weight depending on the type of bird and where the feather came from on the bird. To make 1 pound out of small bird feathers can easily take over 1000 feathers. To make 1 pound out of large feathers from an emu or ostrich can take around 200-500, depending on the feathers.
