Hello, We have some muscovies and want to allow them to raise their own ducklings. One of them recently starting laying in a new spot, and is sitting on the eggs part time rather than full time. She's still sleeping in the coop with the rest of them, and nighttime temperatures lately are around 20. I'm assuming this is low enough to kill the eggs, but wanted to confirm. And if so, what temps are sufficient to keep the eggs going? Until then I assume we should be removing the eggs from the new spot? Or is it best to leave them so that she doesn't change locations? Thanks!
