I just give them a good smack in the head if they get nippy with me. Show them who’s boss!
*just kidding, 😂
I never put my hand in front of their head, unless they are a well-established docile pet, in a calm mood. I also slowly and gently touch their side before “grabbing” and picking them up. (Hook training, but with my hand)
I only have royals, if i had more agressive snakes, I probably would use an object to gently touch their side, instead of my bare hand..
