dehydration

[BeardedDragon15]

i know i post too many q's but 1 more(it is important)--i have had my new beardie for 2 days now and he won't eat and vegetables-i tried giving him zuccini squash,green pepper,and carrots.i put it in there first thing this morning and he wouldn't touch it.i tried hand feeding him. after i took it out he ate 8 crickets and then later he ate 6 more crickets.also he won't drink.i gave him a bath and he hated it and ran around (freaked out) and pooped but no drink.i put dropplets on his back nose head.i left in a water dish.could this whole problem be because i just got him 2 days ago?one ,ore thing.when i got him i didn't notice anyting but now iam looking at his tail and it's cloudy -is he beginning to shed -or finishing to shed.it has not come off for the 2 days i have had him.i gave him a bath and it was still there.is it going to go away?
