and offer an appropriately sized rodent(at 5 foot probably a rat), ideally as thick as the thickest part of the snake, a little smaller is fine. I usually wait a week after re-homing a snake to let them acclimate before feeding, but if the snake is a wild rescue it might be underfed and appreciate some food before then.. Since you already fed it recently I'd wait a week.
