@4 the Birds, When I used the last of my bag a few months ago, I put it in panty hose. I cut the foot off some panty hose so I had plenty to hold on to, then I shook it over the chickens. It worked okay, but this time I just used a little tupperware container and sprinkled it over the rooster. But a flour sifter sounds like a good idea for next time I dust them. Thanks!
@Mickey, I put it in the nest box, so I know she'll get some on her. They were also dust bathing yesterday in it, so I'm confident that they're covered in it! I put it in their house to, they sleep in there at night, and go in when it rains, so they're in contact with the DE in the bedding all the time.
