I don't think he's lazy but it is a little strange that he doesn't want to run around and play after being in the xpen all day. To rule out anything physical, if it were me (and I'm vet-happy according to my hubby lol), I would take him to the vet and get him checked out..maybe do some blood work to make sure all his levels (like blood sugar and thyroid) are ok.
