This is my first hatch and I just got off the phone with the Brinsea company rep. We have the mini advance, and when I set the machine up, I set it up for "periodic incubation cooling" 1 hour a day, as suggested in the manual. Now the company rep tells me I'm not supposed to turn that feature on until day 7. (It says so in the manual, but it is almost casually slipped in at the end of a sentence. Grr.) I have had it on since day 1. Did I just kill my eggs? We are on day 13 or so. I have tried candling but can see nothing, so that's not a help. Second question: Can someone please help me with candling? I have one green (easter egg) and multiple tan colored eggs. I've looked on youtube and read websites but we still can't see inside.
