I didn't start dating them before 2-29.. but I have a good idea the oldest eggs are from 2-25. That will put them just over 2 weeks when I set them all on Saturday. (3/12)
Nice to know that the tilting isn't a huge thing, I've been working a lot of hours so I just do it in the morning and when I get home. And since I've been getting home late.. you'll notice my Olive egg says "cold" on it.. it was so cold when I collected eggs that evening that the 1 olive egg is the only one from that day I'm going to attempt to hatch. It had some condensation on it after coming inside, so not even sure if that'll hatch or not.
I have shipped eggs coming next week.. my first time trying shipped eggs. So I'll probably be a little cautious with those. Heck, I even ordered another incubator so I could hatch them separately from mine..
Oh one thing about the damp towel, it's keeping the eggs cooler than without it. I think cooler is better than warmer, right?
3 day old eggs are better than fresh laid (pH of the albumen changes quite a bit, but fresh eggs are still good to set).
7 day old eggs are still great.
10 day old eggs are good.
14 day old eggs are okay.
21 day old eggs, some may hatch. They have a greater chance of going bad in the incubator if they don't develop.
Eggs that sat in a hot bedroom for over a month are rotten. I bought some that were supposed to be hatching eggs but were actually stink bombs.
Eggs that have deep chilled can still do fine. I've been collecting them in weather in the teens and twenties, as long as they don't freeze they are okay. Do not wipe them dry, or warm them quickly. If they are very dirty and get condensation, pass on them if possible. But if they are clean, just handle as little as possible and let them slowly come to room temperature and air dry.
Storage temps between 55 and 70 are best for suspended animation.
I'm not a shipped egg hatching expert, so I can't be of much help there.
