Dawg53 is the chicken worming expert here so I will let him tell you what to do and with what. I will tell you however I would not rely on DE too heavily. It didn't do crap for me. Maybe it is better to consider it more of a preventative aide. I like seven dust for mites and lice. It seems less intrusive although I have used ivomec pour on twice now to avoid having to dust them. Lazy!
Not sure about cutting up the chicken though! Had to help do that once when I was a kid....blech.
