frontline and mane and tail Pro-tect (benalkonium chloride) spray?

[HappyHenFarm78]

Can I use frontline or revolution on my birds?? If so, what dose? (kind for dogs vs. cat?) and can I still use eggs???

Can I use horse Mane and Tail "Pro-tect" antifungal/yeast/bacteria spray on their vents? It contains Benalkonium chloride 0.125% and label says non stinging, safe for horses, dogs, cats and "other animals". Safe on ''genitals''.

Has anyone paid a company to come out and treat their lawn/yard for pests? and if so was it safe for chickens after and did it work??

Battling mites. ivermectin pour on does not seem to be having an effect. Neither does permethrin powder. (yes and no) still battling mites- see mites walking right over powder on hens butt. Birds free range, I keep coops clean and dust bedding with permethrin powder.

I've bathed severly infested birds, cut off egg-laced feathers. I notice a week after putting on ivermectin pour on on ALL birds regardless of mites seen, that ones I saw no mites on are now suddenly infested. And the ones with lots of mites are getting what looks and smells like vent gleet. I am SO frustrated!!!!

Thanks in advance.
