I am currently hatching out 3 emu eggs. The first one started incubation on 3/28, the second on 3/31, and the third on 4/14. I have slowly been weighing them whenever I get the chance but I am unsure of the formula of weight loss on emu eggs. I currently have them in the chicken egg incubator (they fit perfectly just concerned about when they hatch if they will have enough room). I have kept the temperature between 94-97.5 and I keep the humidity at 35% and then let it slowly fall down to 25% before boosting it back up to 35%. I have brought out the first egg multiple times to whistle and tap on it. We think we have seen it wiggle on a couple of occasions. When do the eggs usually show more prominent wiggling and whistling? Are there other ways to check if they are fertile? What is the equation of weight loss as well?
