Aren't you using a brinsea? Octagon? Mine are usually more uniform beause the eggs are incubated upright, but not quite perfectly even
No, I'm using the Brinsea Mini. The eggs lay flat on their side (the cool thing is that they tell you to specifically lay pea eggs on their side instead of upright), so I kinda lucked out there. I was thinking is it because they are local?? Probably not. Idk!
