Search this forum, there have been many, many threads about mites/lice where you'll find just what you are looking for.

As for me, my treatment routines are on my chicken info site, here: http://jackshenhouse.com/VSChickHealth.htm

Once there, scroll down to 'Worming/Dusting/Spraying'.

If you suspect that your birds have a parasite problem, act NOW, don't wait. Parasites can kill.
