A second egg is pipping.
They are definitely aware of my presence - as I walk into the room and put my ear up to the tank, I hear nothing - until I wait. Then I can hear scratching noises. But if I make a noise, they stop.

So I decided not to photograph the egg that is currently pipping, and am going to try to leave them alone for a bit.
