Good morning all! Momma Muscovy disappeared (predator?), and I now have 12 eggs in the incubator. All are viable. I'm not sure exactly when she started setting, but based on weight and air cell size, best guess is they are approximately 12-14 days along. The lowest weight is 71g and the highest is 84g. The air cells are all fairly consistent in size. They are in a Little Giant incubator with a fan. Temp is holding at 99-100* and the humidity is averaging 33-36%. I haven't added water but will start misting them today. I've been reading the Muscovy egg incubating threads so I think I'm doing thing right so far, but, I'm absolutely hopeless at math. Could someone tell me how to calculate the weight loss percentage in grams for when I weigh them again? Thanks!
