Well, welcome to the BYC forums! I have the same Brinsea (the eco, though, it looks like you may have the advance). That is quite a temp drop, I've never had mine drop like that. Do you have an accurate thermometer in there, and a hygrometer that has been calibrated? 80% humidity sounds pretty high to me, even for the last 3 days. Did you candle on day 18? I would leave them for now, if it is just the start of day 22. I don't have any experience with past due eggs, so hopefully someone can give you some better advice on how to proceed. I certainly hope they're okay.
Edit: Sorry, i see now that you candled 2 of them. You saw movement in those 2? I'm wondering if your humidity the last 3 days has been too high.
