I've used this incubator many times with good success rate. It was all normal till day 10 when the heat dropped to 33 ish Celsius. Its now day 16 and all the way down to 28 and I've placed an insulating bow around it which doesn't seem to have a great effect on the temperature but has increased the humidity to 72%. I've candled and they seem to still be developing. Do they have a chance? If so does anyone have ideas about how to increase the temperature?
