i wouldn't be to worried about using fed-ex to ship snakes i know personally i prefer to send airport to airport for when buying or selling lots at a time as I've had fed-ex loose a few packages for a day or 2 even when they are shipped from the same person might get 1 part the day there suppose to be there then the others might show up a day to 3 days later or at least thats what has happened to me a couple of times in the past
also noticed you said pastel which morph of pastel you got
also if you want to keep just a few to get your feet wet so to speak i myself would keep a few of the babies to raise then breed a few years down the road (mainly this way since like you said your new to ball pythons) this way you get some experience dealing with babies first giving you time to get an incubator at least more if you decide later on you want to expand. it's not really hard to breed and hatch eggs but being new it can seem harder then it is and just like other things some people just aint got the nack for it. or get overwhelmed by it if all goes very good.(then you got way more to care for then you planned on having) or discouraged if stuff goes very wrong (by having most or all die from a few bad beginners mistakes) this way if you take it slow you will set yourself up for success by giving yourself some time to learn the ins and outs of ball pythons in general then stuff about breeding which like said aint really hard but would save you some headaches worrying about if your temps in the bator are right or if the humidity is right. or worrying if and when the eggs will hatch as I'm sure more then 1 person has lost eggs to checking on them all the time there first few times. i know i lost a clutch or 2 my first time (I'm sure due to being new to breeding and hatching. but then again back when i got my feet wet there wasn't all these morphs around or very much info on how to hatch the eggs)
