I have kept chickens for 7 years and I have NEVER used any of the above list.
To keep chickens healthy, you need enough space, good quality feed, and clean water.
Do not add chickens that have been to swap meets, shows or other places where they could be exposed to other chickens that might possibly be sick.
IF you get a sick chicken, I have had one in 7 years, immediately separate it from the flock. Provide feed and water, if it does not get well dispatch it, so that the rest of your flock is protected from exposure.
