Chicken Lice...Ewwww has anyone tried Poultry Protector Spray?

[laurantranch]

I have never had an issue with parasites until recently. My hens (not my other chickens) all seem to have chicken lice as they are close to the vent area and all the feathers in the area look to have eggs on the shafts. I've tried DE in the chicken house and nests and dust them daily (after cleaning out the whole coop), dusting the hens, and I've even washed them down to the skin with Dawn dishwashing liquid and blow dried them...which took a few days to complete that mission. It helped a lot, but I don't ever want to do that again! With that said...anyone try this Manna Pro Poultry Protector or the Care Free Enzymes Poultry Protector?
I will not use any harsh chemicals. Whatever I use has to be environmentally friendly and super safe for my girls. Any suggestions would be very welcome!

you could use frontline plus. it works wonders!!! 1 drop under each wing and one on the back of the neck, prefferably the middle.
