They need to lose 15% (+/- 1.2%) of their weight during the duration of incubation.. and the duration will depend on your incubation temperature.. at 95.5 it will take closer to 58 days (which was recommended to me by a long time emu breeder from back in the emu production days)
and at 97.5 it will take closer to 50 days.
The amount of times to turn them varies by person.. I turn mine 5 times a day.. a male emu turns them a lot more than that. and some people here only turn theirs 3 times a day.
Everything else you have listed is spot on!
Oh one other thing to add.. when handling the eggs make sure your hands are CLEAN or wear surgical gloves.. bacteria and oils from your hands can cause problems down the road such as contamination and oils blocking the pores of the shell.
Try to weigh them at the same time each week. If you put then in at 10 am every week try to weigh them at 10am. I mark the pointy side of the eggs so I know that that mark is always facing me when I turn the egg each time. Sometimes the eggs roll and you will forget which end faces you when turning.
Thank you! All of this help tremendously.
