Thanks! I will do it at beginning of day 19/end of day 18, maybe a shade sooner.If you set at noon, then lockdown is noon. But it's really not a big deal to do it a bit earlier or a bit later. I've locked mine down late MANY times and still have had great hatches. (by late, I mean no more than a day) Ron had one hatch without locking down the eggs.
Seems like I may have to pull all 7 of my eggs from the Brinsea Mini because none of them have progressed beyond a 1 inch wide shadow and today is day 15. I am thinking they were either yolk shadows (and I mistook them for a developing embryo) or early deaths which I did not see because of the dark eggs. Well 6 of the eggs were from Whole Foods anyways so not a big loss. But I still went ahead and purchased 4 light Brahma chicks as a consolation. I am wondering if the Brinsea Mini has any ventilation or not. I did not see a vent and its tightly sealed and the manual does not mention any either.
Fingers crossed on my Brinsea Octagon 20 which is on Day 13 which definitely has a few eggs with embryos and they are moving and kicking. Will post pictures after tomorrow's candling.
