If you choose to keep them here's some quickie advice on the feeding:
If they're not separated, separate them into their own enclosures. Feed them in their enclosure so you don't need to keep moving them back and forth. I don't believe in snakes becoming cage aggressive from feeding in the enclosure so I think feeding them where they're most comfortable would be best.
As Heather mentioned, we need to know all about your husbandry if you plan to work with them and keep them so you can be the best first snake owner you can be. They may be defense striking if they're stressed out from either over handling or their husbandry not being up to par (or both).
