The thought of mites, lice or any other creepy crawlies on my girls is not a pleasant one . So I'm planning to do a pre-emptive strike and offer an occasional dust bath of DE or wood ash - or both. I have read here that many of you do this. My question is: Is it better to offer it in a box or some sort of bucket, or just sprinkle it around the run and coop? My thinking is that if I offer it in a box, there is less waste, and it will last longer. I have a small supply of ash available (not a whole lot in the fireplace), and don't want to keep buying DE, if I can keep using it repeatedly. Thoughts?
