Shouldn't have "cut" the eggs, especially before any pip on their own first, but personally cutting eggs is not something I favor in any event. For one thing,
the "goo" in the egg can dry out & trap the snakes, for another opening the eggs exposes them to mold/bacteria/all sorts of pathogens in such a warm & moist
environment. Also tapping the snakes to get a reaction can cause them to tangle up inside the eggs. Hard to tell you what went (or is still going?) wrong with
these but nature gave snakes an "egg tooth" for a reason...to open their own eggs when the time is actually right.Sorry...
