I am open for any and all advice! I decided to collect eggs on 3/18-3/21 to incubate for my sons pre-k class. With doing my math, day 21 should have been Monday, 4/7 for batch 1 (3/18 collection). Sunday the teacher called and said she could hear someone in there chirping and eggs "rocking". We have not heard much more chirping, but eggs are still moving. No one has hatched, zipped, or even made a pip. The teacher said she was having issues w/ incubator getting above 102, so she cracked the lid to get temp down, which I assume released humidity and could be causing the delay. I do not have a humidity thermometer in their and am hesitant to open and add one.If there is no progress by the end of today, should I candle to see if they have poked into the air sac? I know they are alive because they are moving, but we have 7 on day 23, 5 on day 22, 7 on day 21, a few on day 20 and 19. I know this is "lock down" time, so maybe I just need to be patient. It's so hard when you have lots of pre-k kids itching to see the babies.
