I know everyone worries about temperature in the incubator And I've read and read all I can including threads on here. I have a steady tenperature in a circle air hivabator with 12 duck eggs on day 4 of incubation. But I have two thermometers (well 4, but 2 are off) which are not in agreement. I have an incutherm hygrometer/thermometer combo. I did the salt test and the hygrometer is off by 1 percent (reads 1 lower). The thermometer is consistent, but not as quick to catch up, no way to calibrate. At current temp, it's reading 98.4-98.8, Ave 98.6 I also have a thermapen (meat thermometer!) That the site says also measures air temp. I was able to calibrate it and it reads within .1 degrees. It reads the temp as 99.1 - 100.4, ave 99.75. So, I guess I'm looking for an opinion. Keep buying more thermometers? Trust the thermapen? If the hygrometer is 1% off, would that correlate to 1° on the incutherm? I tend to obsess, and don't want to screw up the babies! Also, everyone has a different thermometer recommendation, and I have nowhere to buy one locally. Thanks for any insight.
