I'm glad to hear he is doing well. They are busy bees when they get going. I was going to say I think he has too much substrate so is hiding more than you would really want him to. It may be an idea to remove and bag some up for later just so he doesn't bury himself all the time. Keep doing lots of the hand to hand running making your hands a little tunnel. Remember he is still a little toddler and they do like to have crazy half hours! He won't be like an older settled hammie at the moment. Be very confident and just pick him up like I showed you. None of this litter have ever nipped and they have been handled from when their eyes were open at 15 days so they are used to it. His brothers and sisters all all doing very well too and I have updates and they are all coming out and being handled happily too
Looking forward to lots of updates.
