Hello Cosmic. You'll find that hamsters are very different from one another. I've had hamsters who were ridiculously tame from the day I brought them home and others who find the changes in their environment terrifying. I've had hamsters who settled in very nicely and were so curious about the human who keeps looking at them and others who will actually scream in fear. The very young ones are usually the ones yelling at me. Very unnerving! You've got some nice advice here. So, slow down and let your nervous little one go at his own pace. He has to learn to trust you.
It's hard, but it pays off in the end.
