Chicken of the woods is a good edible mushroom, but may not be especially tasty, if too large or mature. Usually smaller thinner caps or thick and knobby caps as they first emerge from the wood are better.
Chicken of the woods has an unusual texture, that becomes sort of woody with age. A good young specimen can be cooked in many ways. This one was huge (we took about 5 kg home) but, bit too mature. ;-(
