When i got my first beardies, they wouldnt eat, try starving for 3 or 4 days then putting some live locusts or crix in the vivarium, it worked for me.
As for handling, the i used to just shut my bedroom door, get them out one at a time and sit on the floor holding it, then when it decides to scuttle if and explore, keep an eye on it, give it 10 minutes then pick it up and sit with it on your shoulder, mine used to stay there for ages, actually fell asleep in the sofa with one on my shoulder for about 2 hours and she was still there when i woke up, scared the crap out of me ofcourse lol.
Try to handle them regularly and just make sure there is no way of them getting out of the room they are in
Its easier than you think
