Breeding pairs are separated for feeding and kept separate for a while afterward to give them time to settle and digest. For instance, with ball pythons over the course of a week I'll pair on day 1, separate on day 4, feed on day 5, then re-introduce the male to another female on day 1 of the next week. Adult boas go a month between feedings and digest more slowly, plus they have a longer courtship, so they may be paired for three weeks, separated to feed, give them a week to digest, then reintroduce the male to the female.
Clutches are only kept together in the incubator until all the babies shed, then they are separated into tubs in a hatchling rack and fed a week after that.
Also I dare anyone to come over and move my female 15 foot retic to and from a feeding tub.
