I've enjoyed reading this thread today. I have two Emu eggs at day 49. My first ones.Someone gave them to my husband to see if we could hatch them. I hatch chickens and ducks but never an Emu.
I have been turning them regularly but didn't know you could actually see them move before the hatch date. So I took them out of the incubator today to look them over good. Lo and be hold, I can hear both of them chirping and they actually moved quite a bit when I whistled to them. Absolutely ticked me to death! I had to show my husband as soon as he came home. He doesn't have very good hearing but he can hear them and then saw them move! Needlesstosay, we are excited.
Anyway, I do have a question. Since my Emus are so vocal, does that mean they have broken the air sack? I know chickens start chirping once the air sack is broken, as they are then breathing. From what I have read in this thread, it is not clear if that is the case with Emus.
Look forward to watching this thread and keeping you posted on my babies.
USUALLY it means they have broken through the membrane.. however there are exceptions.. if yours are on day 49 they should hatch any day now
