I was able to separate them last night. That's good news. They were stuck together in a big pile the whole time they were incubating--that's normal. The mother would have wrapped herself around them and incubated them herself.
Here's mom on the eggs
.

This was right before I put them into the incubator. They are stuck together in a clump.

A sign that they are close to hatching is that I was able to carefully separate them. Another sign is that they are starting to dent in a bit. (The shells are leathery and not hard like a chicken egg.)
At least some of them are denting.

This pic was taken through the incubator window so it's a bit murky. There is one huge egg. You can see it in the right hand side. It was the bottom egg in the pile and is a lot bigger than the others. Can't wait!!! :) Maybe it's twins??!!
