Not exactly sure with Diamonds Alex, but before you pick it up, if you are just starting out it's probably a good idea to wait until the breeder has gotten them feeding. Not sure how these guys go taking their first feeds but some snakes can be atrocious to get them to take their first feed so, if they are reliably taking their food item, as a first time reptile keeper this can take some of the stress out of it all and allow you to enjoy your new 'baby' more.
Good luck with it all anyhow.
