Someone needs to make advantage for chickens. Also if you have bad flea infestation on your dog or cat. I highly reccommend triforce. No fleas on any of the dogs.
Ok, I don't know about chicken help, I wonder if avon's skin so soft would work. Anyway back to hijacking, my sister lives in a highly infested flea area and they have had great results with this for her dog. http://www.1800petmeds.com/Comfortis-prod11039.html
I use liquid Diazinon and spray it on, keeping the animals off of it until it dries (I do this in the Spring and end of Summer)...not a flea to be found. Works well for fleas, mites, millipedes etc etc.
It is important that the animals not get it on their feet/paws to later lick. It will make them sick and could be fatal if they get enough of it. Once it has dried you are fine. I would not use it if you free range and the girls can eat the grass with it on it.
