I noticed some friends said the current quality for shuttles are worse than before. It is indeed the case. Few years ago in China, all geese and ducks were feed by natural food， and maybe it would take 4-6 month for a gosling to grow up.( 4-6 month is my assumption). But now, some business man want to get more profit, they feed the geese and ducks by forage which contain lots of hormone, so it reduces the growth circle, maybe only need 1-2months. So the quality of feather getting worse, the durability is declining. All of the manufacturers in China meet this problem, of course the factories can not raise the geese and ducks by themselves.
