We are new backyard chicken owners (or will be). We are going to get our chicks this spring. I am doing a lot of research prior to getting them. I saw a dusting bath mix that uses wood stove ashes. Convenient as we have a woodstove. Question is there are some "charcoal" chunks. Will they be okay fot the chickens? Also we occasionally have to use firestarters to get wood burning especially when wood is wet from rain. Will these ashes be okay for the bath? I am sure we will have more questions as we go. Luckily we live in an area with "mild" winters and not to bad summers. Do get some 100 degree days but area of run & coop is in the shade.
