How is the filling material produced?

 
Ca. 98% of the amount of waterfowl feathers and down produced world-wide are harvested after the slaughtering of the fowl – as a by-product of the poultrymeat production. The consumers are mainly demanding young and tender poultrymeat. Therefore, the animals are usually slaughtered around the time of their first moulting.
