I have bought mini Eco brinsea incubator and as advised to run it for 24 hours to maintaine the temp and the humidity. It's been nearly 4 hours sine I have run it without any water in it but still it is giving me the reading of 52% humidity . I am a bit concern is it the machine p laying up or the 2x hygrometer/thermometer are wrong? I need help as my eggs are due to be collected in 2 days . When I had this machine today morning I have run it with out any water and it drop humidity from 55 to 36 and then I have added 9ml of water to test it and it went up to 53% and then as I have emptied the water bit the humidity had gone down but went back to 52%. Where am I going wrong ?
