He'll be fine once he is back. Long term stress would be something like cohabbing with a bigger snake. Handling is typically a short term stress, but....
This. I have one right now who is having feeding issues. I've had him since mid-April and I've only handled him twice-- once to put him in his rack and once to move him into a smaller enclosure because he was not feeding in rack. He finally took a live rat pup after I made that 2nd move. I won't touch him at all until he is eating f/t for me like I want. Just no need to stress him. Like Jordan said... some handle it fine, some can't. If he loses weight or stops eating... that is when you know it's an issue.
