Okay, my brother got my kids one of those POS incubators... hopefully without quail eggs.... and i've heard that they do ok until day 18. what if, at day 15, i switched them to underneath my giant fluffy hen. Would that work? would it throw her hormones totally out of whack? would she refuse to sit on them? would they be mutants? do you think that the damage that kills them by day 18 is pervasive, or do you think that with a switcheroo it could be avoided?
