Temperature Fluxes - How much is okay?

[Teal]

hellosugaree - Mind taking your WC snake debate elsewhere? It's taking away from the fact that I am asking questions about keeping my clutch alive, which is quite rude. Thanks.

So in addition to the questions I just asked on page one, I'm also concerned now about some discolouration in the eggshells. If they're healthy, they should remain white the whole time, yes? Some of them are, but some of them have clear-ish looking patches and yellow/green discolouration - part of which I believe was from being on coco fiber, but there is some new discolouration forming now that I think might be more unhealthy.
