Eggs could be infertile, my females were laying infertile eggs for months even if there was a male present.
Whenever I removed the eggs, they never made it, because they never ate. But the eggs I left in the parent tank grew off the uneaten food from the parents and the micro inverts that were in the tank, and those grew and morphed.
Just a warning but this specie can be difficult to raise from eggs, they want to go terrestrial once morphed which can be difficult but they also morph very small and can be difficult to raise. If you don't have micro inverts in the parent tank, I would get daphnia if you're raising it in the adult tank, or daphnia and bbs if you're raising them in a separate tank. Personally I just have 2 pieces of floating cork bark in my tank and I remove them when they morph and put them in a shallow aquatic setup with some plants.
If raised in the adult tank, there should be plenty of plants, and adults will really only eat eggs, they don't generally touch the larvae at all, unless the larvae is like sitting on food but they're usually smarter and run when they get near.
Whats your adults tank like?
