Poultry Protector vs. Frontline

[Orpstralope]

I luckily haven't had to treat the problem of fleas/mites/lice but if someone has I've started this topic to get people's opinions of the two, and which works better. If you've got experience, let us know!
Thanks

I haven't used either for chickens. I usually use Sevin 5%(?) to dust the chickens for any external parasites.
