I'm pretty sure they won't last long.
Oh and do you remember that Mavis is sitting on eggs? Well they were fertile and some of them are hatching as I type! Nature being nature, I'm sure they won't all hatch, but I can hear cheeping and I saw one wee, tiny greyish, blackish head peeking out! By tomorrow morning I'll be able to tell how many of the nine hatched. Please keep fingers and toes crossed.
