On worming, I go by Dawg53's recommendations, because he keeps current with this. The only wormer officially recommended for chickens is piperazine (Wazine is one brand) and it only gets roundworms, so you can actually lose your chickens if you're not willing to venture into the world of cattle, sheep, etc. wormers and they happen to have something like gapeworm or tapeworm.
Valbazen (albendazole) is the only wormer that gets all chicken worms, and it is safer because it acts slowly, so it cannot cause the chicken to get clogged up with dead worms, which can happen with other wormers if they are infested enough. It does not kill mites, which Eprinex pour on does, but Eprinex is becoming less and less effective on the worms it used to take care of. And Eprinex does not kill lice.
Valbazen dose: 0.5 cc (ml) by mouth for each large fowl bird, 0.25cc for bantams. Repeat in 10 days. Egg withdrawal is a total of 24 days. It's actually 14 days after each dose, which adds up to 24 days.
There are a number of natural wormers people use, such as pumpkin seeds and cayenne. I have not read anything to indicate any of them actually rid a chicken of worms.

This is the best all around information about de-working that I have read. I'm book marking this. Thanks for breaking it down.
