I wanted to add the following....
When I posted this, I thought she had dropped her egg sac because I saw the white silk wrappings in her burrow, but they were not the sac...yet. She took two solid days to finish wrapping it up. The day after I posted this I tippie-toe'd into the T-room and checked on her using my flashlight to see in to the burrow, and I actually witnessed the eggs being dropped with that weird yellow fluid all over the place.
The egg sac was only completed by the end of the second day. The good news is that it's been a few days now and the sac is still going strong. She has not dumped it into her water dish or eaten it or discarded it - which these T's are apparently well known for.
So yes Martin, positive thoughts and a lot of crossed fingers!
