get some sevin dust and just ruffle the birds feathers as you hold a handful of dust and let the dust slide outta your hand into the feathers. Do the whole bird this way, than just throw some around the coop. On worming, I use valbazen (sp), kills all the worms and you do it twice (10 days part if I remember right) and don't eat the eggs for a month (you can hatch them or cook and feed to your dog and worm them but don't feed back to the chickens)
