I called the feed store for poultry dust and the guy said all they have is sevin and he uses it on his flock. So I send my brother to go pick it up and he comes back with 10%. From what I understand it should be 5% correct? I am thinking I should just return it and try to find a feed store that carries poultry dust. We have been in a serious drought and now it's poring rain so dusting them is going to have to wait anyway!
