Welp, it took a long time, but the eggs hatched.
She laid 6 eggs. The first one didn't make it. She dumped it into the pond about 2 weeks later. I noticed when i was draining the pond, as i do every Sunday.
She later took another egg out and attacked it on the food tray on March 5 or 6 at night and then laid another egg after that,
I took a pic of the 2nd one she attacked and posted it in another thread. I'll edit with a link to it in a minute. It was like a boiled/scrambled egg inside. I didn't see a duckling in it.
i also included a calendar. She started sitting on the eggs full time between Egg 2 and 3, which had me worried, because it was about 30 days already. Going off a 22-26 incubation day, i labeled the calendar with my estimated time for their hatch date.
They all hatched sometime after yesterday morning or afternoon and this morning. I saw whole eggs in the nest yesterday morning when i last checked.
