Today is lockdown and I’m using a new incubator . Chicktec Inca 50. First 18days kept at around 28%.( I’ve always kept first 18days at 25-30 and had good results.) I simply cannot get the humidity above 40%. Temp is 38. Despite programming digital guide to 65%!!! Here’s what I’ve tried today... Tray is full so maximum water surface area achieved. Additional tray added on hatching level with sponge & water in. Small Jar with wick added..no more room to add any further water inside. Incubator is near a radiator . I’ve added humidifying dishes to radiator but should I try turning radiator off? Its the only thing I haven’t tried but I’m in England and it’s around 20 degrees inside when heating is on , 6degrees outside and raining..snow predicted this weekend again so temps will drop..not sure turning off radiator is an option?! Move incubator? Anything you can think of that I haven’t tried? I have 30 eggs in there all candling as potential chicks!
