I'm ending day 28 from my calculations, but not momma's so I could be wrong but from the rocking and what I saw candling I'm pretty certain I'm right on. I've been trying to keep busy myself, but didn't do the smartest thing because curiousity and impulsitivity got the best of me and I had to just know if any were alive or not since I was seeing rocking but still no pipping yet as of 8pm EST tonight. So far all are alive as of 1:30pm, I can even tell which ones are going to have light pink bills because I can see them poking that clearly, but from what I went through last weekend I know how fast that can change. But my humidity level is at around 82%, temp at 98.5-99, so I'm all set for them to hatch, it's just a matter of if/when they want to hatch. As the time continues to go on, even though I know 28 days is a general rule of thumb for ducks, and it can happen sooner or later then day 28, but I'm beginning to lose hope until I see a pip. It will be so devastating if I lose all 8. I've been pretty good with self control and not candling with this batch, but today my curiousity and panic got the best of me, if any were pipped I would not have even opened to check. So, I sit and wait along with you! I wish you all the best of a quick safe rememberable hatching of your eggs. How many again do you have due to hatch?
