Actually, I'm not sure if drastic temp changes would hurt them prior to incubation or not, but why chance it?...store them in the house if you can, just don't store them for more than 7 days before setting them. In the meantime, fire that 'bator up & let it run for a few days to make sure it's holding temp & humidity properly before committing eggs to it. Also, go to the beginning o this thread &start reading; Sally's written or pulled others' articles together to form a wealth of information & tips in this one place...take full advantage of it.
If you have any questions or concerns, don't be shy about asking questions.
