I had 10 eggs that I tried hatching and set them all up according to the instructions. I placed the thermometer attached to the plastic on top of the eggs and the reading was at 99.5 and the humidity stayed between 35-40%. I was trying to bring up the humidity because the manual says 60% is where it should be so I added sponges and was only able to get it to 53%. I left it and the day before lockdown, I noticed condensation on the windows so I went out and bought a humidity thermometer (accurite) and upon placing it in the incubator, it read the humidity to be at 76% and the temp to be 85. I was in shock. Had it been at 76% this whole time and 85 degrees? That is a huge difference in readings. Well, I adjusted the thermostat to 102 and my accurite thermometer was reading 97 degrees with 75% humidity so I left it at that. Day 21 passed and no chicks. On day 24, one chick piped and died trying to get out of the shell. She didn't even try to zip around the shell. She died trying to push out of the hole she had started with. She managed to get one foot out and by the time I decided to help, it was too late. The other eggs look fully formed inside but never hatched. I candled and the air sacs looked a little large on some. No movement. It didn't make sense because I read that late hatches and larger air sacs was due to low humidity. The other problem was that I had the thermometer on top of the eggs and had set the temp at 102 before lockdown which only read 97 on the accurite thermometer. When the chick was trying to hatch, she knocked the thermometer off the eggs and on to the floor, and the temperature ended up reading 104 on top of the eggs when I put it back. Had I known the reading would be two degrees lower on the bottom of the eggs, I would have adjusted the thermostat. I am thinking I will put the thermometer on the bottom of the eggs next time and strive for a 100.5 reading instead of on top where it can get knocked off when chicks start to hatch but I don't know what to do about the humidity problem. I am so confused. I don't know which thermometer to trust. My windows stayed fogged up a little all the way to the end. I want to put another batch in this weekend but was wondering if anyone else had this problem with the LG still air incubator.
