I noticed yesterday that some of my chickens had either pulled out some feathers, or maybe fought and some came out? I haven't seen any mites, but it got me worried. Can anyone give me any ideas on how to prevent or get rid of them? All I have been able to find is info on DE, and I have used it in the past to treat my garden, and it didn't work. I used it to treat my yard for fleas many times, and it didn't work at all. I ended up getting seven dust and treating my dogs with front line. I was just wondering what other methods people use?
