Thanks - yes I have been re-reading the guide. That's why I started calibrating my thermometer and hydrometer. Have everything dialed in now and found that the dry winter air in my basement is real dry, brought the humidity levels up to where the guide suggests and weighting weekly. Have not been misting due to the air cells being to large, misting actually can cause more evaporation.
Running through a new cycle with the Muscovy eggs getting everything just right before my geese start laying again - Found a frozen goose egg today that the girls had covered up, should start laying soon.
You know, having accurate temperature and humidity readings seems to be the biggest challenge all the way around. I am glad you figured out about the humidity: Is your central heating equipment down there by any chance? If so,a furnace will take almost all the moisture out of the air. I remember how dry the air would get once the furnace kicked on when I lived in Ohio.
In addition to weighing the eggs, I candle the eggs about every 4th day and use a pencil to mark the air cell. Till the last couple days, when the air cell dips, their should be fairly incremental increases..no big jumps or large segments. I plan on buying a digital scale to replace the old kitchen scale I've been using (used for measuring baking ingredients) since it is not terribly accurate. It gives me a ballpark, but nothing more.
I just ordered a gadget to check all my thermometers and my
Brinsea's digital temperature. It is a Precision Frio-Temp Digital Verification Thermometer. It comes with certified calibration certificate and is guaranteed to be within
.5 degrees F of the actual temperature from -58 to 392 degrees. The probe is in a glass jar filled with some sort of media that evens out the temperature so a uniform reading can be obtained. That ought to help me correctly set the temps for incubation. So far, with chicken and turkey eggs, I've had 100% hatches this year. I just want to be more careful with the goose eggs since they seem to be more fragile.
Sorry about the frozen goose egg: That is a bummer. I am sure your girls will give you more eggs soon. Also, good luck with the Muscovy eggs!
