A couple things....
1) I talked to Sally Sunshine! And the answer was quite obvious...re: humidity and shipped eggs. Shipped or local, no difference and there's no set %, go by the air cell. If the air cells are fresh and small start dryish, if the eggs are older/bigger air cells add a small amount of water and candle on day 7, to make adjustments as needed. But no advice specific to shipped eggs. (Some of my eggs will be 7 days when I set and I'm thinking of running 35-38ish % and see from there).
2) I haven't set the shipped eggs yet. I haven't even touched them but I would like to set them soon. I have these 2 quail eggs in the incubator. Tonight comes to the close of "hatch day" but no pips. So I candled. They are a greenish hue and very speckled, so really hard to candle. One quit. And one looks good. So I tapped on the air cell end with my finger nail and it tapped back!!!! Does that mean it's pipped internally?? No peeping. I can't see a beak in there. But the egg moved in my hand 100% and tapped. No external pip. Should be soon, right??
3) I almost forgot to say, I told Sally about the thread and asked her to stop by!
