Is my bearded dragon sick?

Sounds like your bearded dragon is stress. Also, in the wild, almost anything can really eat a baby bearded dragon, so it's just acting naturally. Bearded dragons also love to roam, I often let my bearded walk around my baby proofed room. And it almost never claws at the gl. Also, when u hold it, just let it rest on your finger, or your hand. It should hold on to you, u shouldn't hold on to it. The extra skin may be that he isn't shedding well. Do u have a bowl which he can use to bath in. Also, alot of the time when reptiles shed, they refuse to eat so not eating is normal. Another thing, do u feed him a balanced diet? Vegetables and fruits? Calcium coated crickets. Vitamin covered 2 times a week? This could explain his Poop.
