I know one thing that I have found out. You need to put in some moth balls in with you feathers if you don't use them alot. I have several of my goose feathers that I don't use often, and they have gotten eaten up by small mites. I found out the hard way to put in some moth balls to keep them out. Works great! Have several plastic containers and tool boxes with a couple of big drawers full of feathers and supplies...
