Quote: I dump my wood ash here and there in the yard/garden. The chickens love to pick out the little black crunchies. If you have stove ash available, they will do what they want with it. They will eat the nuggets, they will dust bathe in the ash. I have no concern about them "eating too much". If they have free access, they will eat what they want, when they want. That applies to just about everything in the yard. Including the rhubarb leaves. A number of us have found that chickens devour rhubarb leaves, but only in the late fall. I think they are self medicating, as articles have been written about the antihelminthic properties of rhubarb leaves.
