Well she just kept getting off the eggs a bunch today and being off for long enough periods of time that the eggs never got much warmth. Which also said she wasn't on them very much.
Due to her behavior today and seeing her actually sitting in the bedding in front of the nest box I made the decision to take the other 2 eggs I'd given her. She was sitting on them, but not well and I didn't even have to lift her off them. She stood up and allowed me to take them. They were just barely warm which means she'd only been back on them a few minutes and that means she was off them over over an hour.
So I took them, candled them to check for movement (there was), marked the air cells, which weren't much progressed since day 14, and put them back in the incubator. Hopefully they'll survive. *fingers crossed*
