I just weighed mine for week 5. It is so weird to keep turning and weighing and have no idea what is happening inside! I thought I saw some movement in a couple of the eggs today, if it wasn't my imagination. Good luck with yours!
Wow, that is a monster egg! The seam around the middle is cool too. I am incubating my first emu eggs and read that they pretty much bust out of the egg at the hatch, rather than zipping like most birds. Maybe that will give the twins better odds? I am always hopeful and it is fun to try...
