Just so you know, it's not a good idea to feed a snake (especially a hatchling) immediately after it's been through something stressful like that and is dehydrated. Better to give them a few days to reacclimate so they don't regurgitate. And then the first meal should be small. Maybe 3 pinks is small for the size of your specimen - I don't know how big it is.
And if it's vertebral column is still protruding it might be a good idea to get it a shot of lactated ringer solution.
I'm sure you did not hurt your snake, but it's better to be safe than sorry. Hope I did not come across as flaming or anything.
