Hello and Happy Friday Can I put Diatomaceous Earth in my coop with my chicks at six weeks of age? It seems safe enough, but I have never raised chickens before so I am learning. I do not think my tractor supply store carries it either. The tractor supply store told me that when my chicks arrive they do not come with vaccinations, but that when they arrive they put the medicine in the water. They told me not to be concerned. Please help the beginner.
