aww your girls are cute. ive only got boys myself, want to swap one? j/k
ok everyone seems to have things mostly answered for you. if you want to tame your new family member take things steady. the more relaxed you are the more relaxed he will be.
choose a time to handle him when things arnt so chaotic, i know this isnt ideal as your girls want to get to know him but trust me its better in the long run, even at this age it does hurt if they bite you and they can even leave teeth in the wound.
Boas are more prone to mites than Pythons but that isnt to say they dont get them, most pet store pythons run the risk of getting them and they make the pythons cranky. Ball/royal pythons are bad shedders, they need a small enclosed area to go and hide in before they shed, thats warm and damp. i use a box thats lined with moss, they tend to stay in it for a few days and then come out and shed there skin.
as Lori P said they can be difficult feeders especially when they have been moved around and tend to need settling before they will eat, if you have any trouble getting this snake to feed i would suggest cutting of the rear of the Foods skull in order to trigger a feeding instinct, something about the smell of the brains is pretty much an appetiser for these guys. when he becomes used to you and being fed i would recommend moving him into a dry box for feeding as these guys can get impacted although its rare.
Congrats on your new friend, im sure you will have a lot of enjoyment form him as we do form our little man.
