How to incubate brev eggs?

[exodus5139]

I want to start breeding my brevs but I wanted to see if anyone could give me detailed instructions on how to incubate the eggs once you dig them up. My friend gave me and incubator, link below. Would this work for pygmy eggs? What temp and humidity do I need to keep them at? What substrate do I keep the eggs in? How long do they take to hatch? And anything else important I might have forgotten.

Also, both my females have been digging in the corners for a few days but they are digging where the substrate is only 1.5-2 inches deep. Should I throw in more substrate so they can dig deeper before they hit the drainage layer?

"Eggs have been successfully incubated by leaving them in situ and also by removing them from the tanks and incubating them at room temperatures that varied between 67ºF and 87ºF. Both methods yielded 100% hatching rates. Incubation times were from 60-75 days."

Question?: What should Brev eggs looks like (during incubation, moreso towards the end)? Should they be solid in color or somewhat translucent?
