I feed my babies about 5-7 medium sized crickets a day, depending on howmuch they eat. I use the rule, if all food dissapears, I add another prey item the next day. Some days they will eat 3 while other days 6-7.
If you don't feel a hard lump and he has been eating like you said he has, perhaps you have a subtrate pooper. (one who poops under his burrow and kicks it under it) Has he moved spots at all?
If he hassn't, check underneath him. Weekly soaks are never a bad idea, but since you don't feel a lump on his right side, I wouldn't add honey, just give him a luke warm 30 min soak and in the meantime, flip his subtrate around hunting for poop.
