Is she eating? If the answer is no, then no worries. Just peek in once in a while, and you just might find eggs. Especially right after a thunderstorm.
Some of mine are still locking, some of mine are ovulating, and a couple have already laid eggs.
I have been breeding balls for 3 years now, and I just photographed my first definition ovulation yesterday. I MISSED all the previous ones, lol.
I try to leave them alone as much as possible at this time, as it always happens that when I haven't checked on them for a day, I come in the next morning and find eggs. I think they choose a time when it's quiet and they're undisturbed.
If she is still eating, but is refusing the male...well, keep an eye out just in case, but chances are lower for eggs this year. You should have the temperatures back up by now, by the way, so do that, if you haven't already.
I didn't cool mine this year--and so far, the results are fantastic. We'll see how it compares with last year, after the eggs are all laid.
