I haven’t been trying to incubate eggs for long and the first incubator I bought was a Kenonnix. The unit said 99.5 degrees but my digital thermometer said much less. Then I brought in a Smart Incubator as it’s very inexpensive. After setting it up my thermometer showed it was at 99.5 degrees so I learned my Kebonnix was wrong. I should have returned it when I still could but lesson learned. I’ve ordered a 2nd Smart Incubator and I have a larger Mikiroy incubator. Maybe now I can get some chicks on the ground!
