I use this powder for my chickens and ducks, I would recommend it to anyone thinking about buying it
Great stuff, it covers all I need to do for our Chickens without having to purchase other products separately such as Diatomacious Earth. Will continue to use this product.
My chucks were infested with red mite last year. I killed them with a very expensive powder and bleached the wooden hen-house to make sure.
I am now using the powder as defence and so far have not been reinfected. I cannot say yet whether it works, but I do not know that it doesn't. I hope I will not be commenting that it does not work!
