Hi guys! I'm using a Farm Innovators Pro model 4200 with the fan and turners and it keeps doing weird stuff. It will hold steady on humidity and temp right up until the first egg hatches. When the first chick is out of the shell the temp starts dropping. The humidity holds steady, but the temp will drop at least 5+ degrees. Once the temp drop occurs, the hatch starts ending. The second to last hatch, I tried to stand over it adjusting the temp to keep it steady and it did not help the hatch rate. This hatch I used multiple thermometers and had the incubator itself in a closet so there would be no outside interference. It still happened. At lockdown I had 21 eggs with embryos but the hatch itself only lasted about three or four hours after the first chick hatched. I ended up with 9 chicks. I'm not opening the incubator. I'm making sure there are no air gaps around the edges. I'm not taking out vent plugs. The temperature in the closet remained steady. It just keeps happening. Are there any problem areas or things that could or should be checked out? I'm happy to provide any pics or information somebody might need to make a guess! Any suggestions are appreciated! Thank you in advance.
