If the embryo is dead, you may have felt it shift. I'm not saying that is albumen, or that your embryo is dead. Albumen oozing through the shell would be white, not yellow. I've never hatched an Emu! I'm merely guessing, based on my experience what may be going on. If I have any thing oozing out of an egg, it indicates that the egg is dead. How does the egg smell?
And, unless you have calibrated your thermometer, it is not calibrated. just because a thermometer says something, you can't believe it unless it has been calibrated against a good thermometer which is known and guaranteed to be reliable. I use a good digital medical thermometer which is guaranteed to be accurate to +/- .2*F, and calibrate in a cup of water to 100*. My other gold standard thermometer is an ancient mercury rectal thermometer which has a very slow response but is spot on re: temp. As for your hygrometer, did you do a salt calibration?
