I've had a couple snakes with deformed ribs before, but never one with newly broken ribs.

In any case, I would recommend feeding him smaller meals that he can swallow easily for awhile. See how he gets around, if he's moving all right... feeding is always going to be the real test. If he eats, how he eats, etc.

As always, get him to the vet for a check-up, just to make sure nothing's poking in a bad spot.

I've found that snakes are incredibly resilient creatures... they can live through a LOT of torture (sadly). Sounds like your little boy just needs some TLC and he'll be back in good shape in no time!
