Quote: I don't worm my birds...never saw a reason to and if I did I would get a fecal test done before choosing a wormer.
Wazine only kills round worms...(and maybe tape worms?)
I don't treat for external parasites either, unless I see them.
Have had to treat for lice twice, I take them off roost at night to treat so no 'catching' involved, used a permethrin powder worked great.
