Well, I bet you're going to get a lot of advice to leave him be for a few days...
But admittedly I never do. I always handle them a least for a couple minutes of introducing the hand within the first 24 hours. I have the tamest robo I've ever heard of. I'm sure it's her nature, she sleeps with me for hours during the day and is very affectionate, but handling her right away didn't ruin her adjustment to the home.
Taming a robo can be a long process
but they are very fun little hams!
Bugatti is very cute!! Good luck taming him and congrats on adopting him!!
