Highly active snakes are usually caused by 3 things. One being their stressed form a new move, two they are Hungry, and 3 its mating time.

Being yours is young and new to you the stress is your factor as to why their eating like this. Offer again in 5-7days in their own setups. Do not remove them at all.

They do not associate your hand as food when entering the cage. Its a myth made up by some crappy pet stores.
