Humidity is probably as high as you can get it.
Temperature is either the standard 99.5 or if your hatcher is quite full, drop it a full degree. The idea is that the embryos are generating a lot of heat on their own.
With most birds the temp should be at 99.5 in a 'forced air' incubator. Humidity should be around 60 to 65%. Do you have independent thermometers and hygrometers, that have been calibrated? or are you relying on the incubators digital readings?
