Welcome Shannon and Peatree. You did the right thing in leaving his cage the same as it was before. As stated before, it will take time. It will most likely take lots of time. I am thinking months, if not years. Now, there will be small steps as you go, but it will be a long time before you have a happy, healthy Grey. You are doing great with giving him new and better food. I would go a bit heavier on fresh veggies. Remember no salt or sugar in what you give him. Also, no caffeine, fruit seeds or peanuts. Thank you for taking in a teenager - we all know how difficult they can be! LOL Looking forward to hearing all about your adventure.
