Morning. Glad they are replacing it for you. Hope that fixes all the problems and you get it up and running like it should.Morning.inkbird is sending me a new thermostat.
I'm at yet another crossroads between waiting on parts to get the incubator working and possible viability of eggs. I guess I can eat the eggs I planned to set this weekend. Or refrigerate them. Arg. Gonna be a twisty turny path today.
Trying to stay positive. Hope y'all have good days.
There's this kid in LA I'd like to introduce you to.....
pretty!!!
This is a splash poliwh I had last year her name was Francesca
GOOD LUCK!! what did your weights look like this time?

Understanding the Air Cell
The average chicken egg has thousands of pores running through the shell allowing the embryo to exchange oxygen, carbon dioxide and water. Soon after an egg is laid, a small air bubble or “air cell” forms in the large end of the egg from water loss. Humidity levels in the incubator determine moisture evaporation during the 21 days of incubation and hatching. The air cell is crucial for the chick to break out of the egg shell at the end of the incubation period. The chick can drown if the air cell is too small or the chick may be retarded in growth if the air cell is too large. This is why maintaining the proper humidity is crucial. Slightly lower humidity levels are more likely to be less disastrous than slightly higher humidity levels.
MARKING and OBSERVING the size of the air cell is a way of checking for correct weight loss of the egg and is commonly used. However, this can be inaccurate due to the different, types, shapes, and ages of eggs. The protrusion of the embryo into the air cell also may effect observations. Again, it is the most common method for non-commercial hatchers. With experience you can adjust your humidity as needed by visual inspection of air cells. However, Weighing is the MOST accurate. If the incubation humidity is too low (very dry conditions), the air sac will be larger than normal and the humidity in the incubator should be increased to reduce the rate of water loss. If the air space is smaller than normal then the opposite applies.
Eggs should lose approximately 11% - 12% of their mass at 18th day of incubation. To monitor mass loss, a person must keep track of an egg’s weight. Optimally eggs should be weighed right after they’re laid, but this isn’t always possible. When eggs are shipped, weigh them as you remove them from the package. Keep in mind that the eggs will lose some of their mass during storage. According to Aviagen, eggs lose about 0.5% of their masses per week in storage.
WEIGHING EGGS
Chicken eggs need to lose 13% moisture. Weigh all the eggs on the first day, before you put them in the incubator and weigh again days 10, 14 & 18. Several formulas can be used to determine the rate of weight loss or overall per cent weight loss and to correct the humidity if the values are off. For accuracy, a digital scale should be used which can weigh in grams. Don't forget to subtract the weight of the container holding the eggs from the total weight when calculating the average egg weight. If you use a rack to incubate your eggs it is best to weigh the entire rack instead of each egg to get an average. If you are incubating SHIPPED eggs upright in a carton you will also weigh the entire carton so that the eggs are not disturbed.
Some Explainations from cochins1088 on weighing Eggs!
How to Calculate Mass Loss
First subtract the current weight of an egg from the original weight of the egg. This number will give you the weight loss. Then take the weight loss and divide it by the original weight of the egg. This will give you the fraction of weight that was loss. Lastly, multiply the fraction of weigh loss by 100. This will give you the percent of mass loss.
For example:
Original weight (50 g) - Current weight (45 g) = Weight lost (5 g)
Weight lost (5 g) divided by Original weight (50 g) = Fraction of weight lost (0.1)
Fraction of weight lost (0.1) multiplied by 100 = Percent of weight lost (10%)
For those of you who incubate large numbers of eggs, you can weigh the trays to find the average mass of each egg.
For example:
If a tray weigh of eggs initially weighs 700 grams and the empty tray weighs 200 grams, than the eggs must initially weigh 500 grams. If there are 10 eggs in the tray, then each egg weighs approximately 50 grams.
Let’s say that 2 eggs are removed because they were infertile.
After 18 days, your tray weighs 560 grams. If you subtract the weight of the tray (200 grams), than the eggs must weigh 360 grams. There are 8 eggs in the tray, so each egg weighs approximately 45 grams.
With this example, the eggs lost 10% of their mass by day 18.

Note: Kitchen scales work great. The WeighMax Pocket Mini CD Digital Scale below works great if you weigh individual eggs. I pasted an egg carton cup firmly to hold the eggs. Be extremely careful not to tip your scale and crack your eggs!

I'm so behind, as usual... @LocalYokel , I dknt know if there has been am update on your dad (apologies if I missed something big), but, you've been in my prayers. I lost my dad, suddenly, the day we got this house, on horse property (affording me this chicken madness), in September. I hate you're going through this, you seem like such an awesome son.
Good morning everyone else...
Came home yesterday with a fever to find the incubator up to 101 with 21%... I added water and led red the lid to cool down... We'll see. It's back to 100 and 40%
I thought that they were supposed to lose slightly more than the 13%-14%?WEIGHING EGGS
