Odd update. So last night she woke us up at 2 am. Her nest is in a window box by my bedroom window and she jumped up and thumped into the window.
When I watched her, she was moving two eggs and I had read they will sometimes move duds so I watched which two. She had also gone in the pond and before last night had NEVER gotten off her nest except one time in the AM when I brought out corn...
Anyway so this morning I decided to take the two she had pushed aside, went to my compost, dug a hole, and dropped them in one by one (just in case) and sure enough they were not fertile (not surprised) so I buried them.
Well I just looked outside and she is standing up on her nest which is unusual. I went over to the window and thought "oh she rearranged her eggs into a nice neat circle... wait, where are the other eggs?" She had 10. I took two. Now there are 6. She's standing up and talking to me, looking at her eggs. I wonder if she realized they were duds and she's there but abandoning it, too? I went outside and no sign of a smell. There is what looks like a dropped egg (but no shell, but yellow) near her nest. Hmmm....
