Baby red tail boa behavior

[harlequinnz]

So I've had my red tail boa for over a year now, and when I got him he was just a baby, the place didn't give me an age, but I knew that he was about almost a foot long, now he's almost 3 feet. I know that his sizes might not help, but Anyway, I was just wondering if a baby red tail boa being hyper and kind of throwing theirself around is normal behavior? I hope he doesn't have any neurological issues. He slithers just fine, but when I hold him, he gets hyper for a little while then calms down. I have another snake but always wash my hands after/before handling the other. I know it's hard to diagnose any of those issues without going to a vet, but I'm not in any sort of situation to take him to one due to financial issues. I do research and find nothing. Also he mostly stays on his cool side. He goes to his warm side maybe 3-4 times a month, and idk, just need some advice maybe lol
