ok? I got some of that powder that you add to water to feed plants. It's like the miracle gro in a box only it's not miracle gro brand. It's some generic looking brand. It's ok to use on vegetable gardens. I wasn't sure about using it on dirt where the chickens have access? I can't imagine that people with free ranging chickens never use this kind of plant food somewhere in their yard but thought I should make sure others haven't had problems with it.
