I finally talked my DH into holding my roo down after dark so I can check him for mites (as people suggested on this site...THANK YOU). HE HAS MITES!!! So gross!!! DH held him down while I shined a flashlight on his rear and I moved his butt fuzz away and there they were. Lots of little black mites. I carried a cup of DE with me when I went out there and when I saw them I dumped the DE on him and rubbed it all over him. I hope that'll kill them. Is that all I can do? I hope the DE works. I actually started mixing a tablespoon of DE in a cup of water for me everyday and now my cats get a big bowl of DE water to drink everyday too. I love this stuff!!!
