Day 21 Update:
Okay, so nothing was happening AT ALL throughout day 20 and we were getting pretty discouraged. I did slip my most accurate digital thermometer probe back into the incubator early in day 20 since I overlooked adding it back after the final turn on day 18 and start of lockdown

. To my dismay the temp was indeed running low, so throughout day 19 and into 20 the incubator was running around 97 - 98 F. Okay, nothing drastic, but certainly NOT OPTIMAL. All this got us really discouraged and irritable, to say the least. Begrudgingly we went to sleep.
Woke up for a good start into day 21 and saw temps and humidity had tanked again

. Thinking air conditioning kicking in overnight sucked ambient humidity out of air as well as keeping things on cool side. Temp was again down to the 98 level and humidity was at 51%. Got really discouraged and down. Went to squirt the sponge on side of incubator to get humidity back up and heard the first CHIRP.

e
Dismay started to turn. Got incubator back up to 99 - 100 F reading on trusted thermometer and humidity back to 65% level (60% was target, but 60 - 70 level is very acceptable since dry hatch method was used). All this chirping started happening at 5:40 am. First pip occurred at 10:53 am (logged)

. Officially our day 21 ends at 7:30 pm. As of right now, 7:00 pm, we have lots of chirping still going on and a total off three pips.
Pip Count:
Barred Rock = 0
Delaware = 2
Maran = 1
Eggs are arranged in incubator according to breed and BR section does have chirping so I think these numbers are going to start changing in next several hours. Due to temps. the hatch will certainly not be uniform and most likely delayed at least 24 hours. Hopefully lots more pipping tonight and hopefully some zipping tomorrow afternoon
