Don't worry Egghead, I am sure you and your eggs will do just fine.
Just remember that sometimes shipped eggs don't hatch even after developing, I have been learning with shipped eggs also, and it is very frustrating at times.
Just don't be hard on yourself for things beyond your control if your hatch rate is disappointing. I also have a very porous egg, I can't tell if it is developing or not I have almost thrown it out a couple of times,but.... I thought I MIGHT have seen a shadow move, soooo .....
Time will tell.
KZ, I had never heard of or thought about cheese cloth in the incubator. I will be interested to hear what you think of it. I have a mesh shelf liner lining my incubator, the waffle pattern lets the air still flow, and gives them a soft grippy surface.
I hate lockdown, nothing to do but wait, and I'm not very good at that!
