I thought about using Wazine, but I don't want to put poison into my birds. So I found this today and wanted to know if any of you use it and what were the results? http://www.theholistichorse.com/Poultry.shtml It's called WormGuard Plus. I have no idea where I could buy food grade DE. I actually was looking for it last year to put into my garden because slugs were eating my pole beans and I couldn't find it any where. If you could direct me to a site that sells it for cheap it would be much appreciated. I'd also like to know what stores sell it. Thanks!
