I finally got some DE from the feed and grain store. The only problem is I'm not sure how much to mix with their food. Or how much to sprinkle on their bedding. I can't really mix a entire 50 lb bag at one time. I keep the feed in a larger container and fill a 5 gallon bucket with feed to take out to the coop. If I fill the 5 gallon bucket 1/2 way full of egg maker.... how much DE should I add?
