Sheralyn,
Hatchling maccies(and most pythons for that matter) will definately eat each other, regardless of whether they have just been fed or not.
I've had hatchlings housed together for months without problems then come out one morning to find one has eaten the other. Quite often it can be fatal to both snakes so I would definately make the effort to house them seperately.Once they are adults you could possibly get away with housing them together but again you'll need to seperate them at feeding time.I don't reguarly house any of my snakes together,much easier to prevent any problems than try and seperate two adults intent on eating each other.
