I’ve just seen your other thread about your cage & there’s some good advice there that should help.
Plenty of enrichment in the cage which is great but it is important to make sure your ham has the basics first so do try make or buy a better house for him, one that is large enough & really dark inside, no base & lots of substrate underneath, if you get a house like the Rodipet ones with the roof that lifts off it makes it a lot easier to just check on them now & then & you can use the roof of the house as a shelf which is better than using the plastic ones that come with cages.
You might find that just making a few simple changes could help to build up his confidence without him being so inaccessible you can’t keep an eye on how he’s doing.
