I heard that red maple trees are poison to goats. Is this right? I have one in my back yard where they are fenced in at. I pick up the leaves that fall everym morning. But know some will fall during the day. I really don't want to cut the tree down because next year we are building and will be moving the goats there. It is a nice shade tree. Is a few going to hurt them? Or will they not like them and spit them out?
