Every year, what's left of our giant oak tree that split in a storm several years ago grows chicken. Chicken of the woods, that is. An edible mushroom, Laetiporus sulphureus forms on the wounds of trees, mostly oak, and leaves the tree in even worse shape than it was to begin with by causing brown rot.
Some years, we have bigger clusters of it than others; this year it seems to be average-sized. I've never been brave enough to try it, though it's supposed to be one of the few that is safe for beginners because of its easy identification. Since it is said to taste like chicken (thus, the common name), I wonder if our chickens would eat it. There isn't much that they won't eat, but if this tastes like chicken, would they want to eat something that tastes like THEM?
