I think they're done mating...It's not unheard of for snakes of any kind to attack a mate, & since they're not "social" animals normally it's best to keep captive-breeding to a minimum to get the job done, since they cannot get away from one another under these circumstances as they can in the wild. It's hard to keep an eye on them 24/7- breeding snakes is not risk-free.
I hope yours heal up okay- I suggest Betadine (povidone-iodine) diluted to look like "weak tea" or Vetericyn brand antiseptic ointment for reptiles, BUT IF the wounds are deep, see a qualified herp vet for help. Remember that snake bites can leave teeth embedded, & in your snakes, that could result in a serious facial abscess if not dealt with, which can impair eating, breathing, & if infected, could spread to the eyes, brain, etc. Face bites should be taken seriously, IMO.
