I have a little giant still air incubator. It's been holding 99.5 as directed. I have read that it should be higher for the still air model is this correct and how will it affect my hatch. Just started lockdown 14 eggs all which were candled. Also now that I removed the turner what temp should it be. I have 2 thermometers both with different temp readings. The digital one reads 99.5 and is located on the metal mesh even with the bottom of the egg. The glass one reads 101 at the top of the egg. Questions is where should I pull the temp reading bottom, middle or top and what is the proper temp. My humility is currently 70%.
Yes, still air should be 101-102F with the temps taken at the top of the eggs. So, it sounds like yours are good. The temps don't have to be changed at hatch time, though some people do prefer to drop theirs a degree. I personally never adjust, but for 2 years I've used an LG 9200 and you don't try adjusting them any more than you have to...lol
If temps have been a tad lower over the course of the incubation, you can generally see a slight delay in hatchtimes. If it's extremely lower you see higher probabilities of developmental issues, mortality and late hatches. Temps slightly high can cause early hatchers, significantly high, developmental issues but more likely death.
Your humidity looks good. If all your instruments are accurate, I'd say you are on the right path. Good luck!
