My prediction would be that they give birth to some monster types more frequently than others, but indeed any monster other than extremely high-ranked ones (particularly Lilim), or ones that appear to be originally fully artificial could be born through an Echidna.

Or maybe if their ultimate consort/husband had a run-in with a particular monstergirl type that didn't end with him becoming their husband (or the echidna is fine with a harem), she'll be more likely to give birth to monsters related to that particular monster.

As they're the 'mother' type-monsters, it wouldn't surprise me if Echidnas had several methods of carrying out a pregnancy to term. Like, live birth, egg-laying, and laying eggs that are filled with seed-like matter for plant-type monstergirls may or may not all be possible.
