Oh how wonderful, look at those little peeping sweethearts. Do you expect the other . . . 2, was it? . . . eggs to hatch? I guess they would have already if they were going to.
From what I've read about incubating eggs, it seems like having the humidity just right is a big factor - I'm wondering why that doesn't seem to be a factor here. Doesn't sound like you have any source of humidity in there? Have they been hatching with no problem? How many are there now?
