believe or not they like charcoal
Might be worth posing the char/deer connection to a wildlife biologist. I have heard accounts of other animals eating char before with the theory that is has a detoxing effecting. I don't imagine they think of it in such a cerebral fashion, but if the animal is experiencing some indigestion, it might be instinctively compelled to seek out and consume char.
