If they get over revved up we would end the session and put them back in. They can get over excited and bite at that point. We don't tend to hand feed food but instead put it in a dish in the cage and set them down near it to get their treat. It was likely because your hands smelled of food he bit or over excitement as you say. They are like toddlers and need to learn to be calmer and that they won't get food every single time. They soon ask to come out just because they enjoy it.
Our screetcher who arrived today called Treacle has actually stopped almost already now she realises that screetching does not scare us off from picking her up. She is but a little diva!
