Round 3 incubation went through the 22nd day and of the 24 eggs candled on the 10th day 15 hatched. 2 Barred Rocks and the remainder are barnyard mix. One chick hatched at the end of the 20th day, 7 hatched on the 21st day and 7 hatched throughout the 22nd day. Nice to have a fair hatch and may want to raise temperature on the next incubation so everything hatches on the 21st day. The humidity level was in the upper 60% when 1 cup of water was added and steadily dropped as it evaporated within a 24 hour period. Interesting I had to add water almost daily, verses the previous incubation's I didn't add water daily.
Three thermometers were placed inside the incubator for comparison and wouldn't you know each had a different reading by 2 degrees. The oldest thermometer with the 99.5° reading is what I used to adjust the Janoel8-48 thermometer and this thermometer is reading lower than the other 2 new thermometers. I may need to adjust the Janoel8-48 thermometer for a the next incubation to have a completed hatch at the end of the 21day.
