Great job selecting the gardstar! i have never heard of a lice/mite protector , not saying whether it works or not. any birds in contact with the infected bird must be treated , and retreated in 10 days or you will see the lice back in the flock.
Have you identified the bug through the link i posted ,once you know exactly you can know more about whether to treat the nesting boxes or coops. certain external parasites can live off of the host (your chicken) and some cannot.
