Glad you took him in and welcome to the wonderful world of bearded dragons, where things aren't always as the seem, lol!!!
He may have a little relocation stress with the new surroundings and all.
Can you give us the background story along with details of his housing like, lights(uvb and basking), temps, hours of the day he has lights on, feeding habits, substrate and size of the enclosure. All of these things help us help him, as they are very important to his health.
Pics will also be a great help you can post them to this link https://www.beardeddragon.org/useruploads/ then add the to you post using the XIMG tab to attach it to the post you are making.
