I am on day ten of hatching some very pricey Crele Orpington eggs. I have hatched them before as well as a few other batches and all have been shipped. Also have hatched some of my own eggs all with great success, had a 100% hatch rate once! My question is about my air cell in these eggs I'm incubating now, which are on day ten. I have never had eggs with possibly detached or separated air sacks, until now. They look as to be what I see others call "saddle shaped". What really makes me nervous is that I see no veins in any of the eggs(9). I did read that someone said they have had some clear ones be sneaky that by day 10 looked clear and by day 14 the egg was mostly dark with a developing chick. I can admit that my humidity is 38-42 and I probably should get that up 50-55 as I just read that humidity could possibly help the air cell, is this true? Also my thermostat is very touchy. Temp is going between 98-100. I feel as if that is okay, if I try to adjust t-stat it will jump to 102 and then I freak and back it off and then it will be 97-99. That's why I don't want to touch it. Any advice would be greatly appreciated. Ps: I did let the eggs sit for 24 hrs, at room temp. point end down before I incubated.
