i removed the one over the fan but found it let my temp fluctuate more then I wanted so I put it back in. but this was just my personal experience. also during the hatch I lost two chicks I feel cause the humidity dropped to around 30%. found it was cause one of the glass windows had started to fall out while I had the lid off and didn't notice it. the membrane dried out and they got stuck in the shell why'll I was at work. hope this helps. my first lime using the foam incubators. have a metal one got from sears many many years ago.
