Why is Egg gaining weight?

[emu6200]

Hi

I have an egg and I weigh it everyday and it is losing weight but today I weighed it and it gained one gram. I keep the humidity 30 to 34% but it only gained one gram today. It's an emu egg. Why is it gaining weight? Is this okay? The problem could be caused from an inaccurate scale reading.

Thank You!

I would guess an inaccuracy in the scale reading, but @Pyxis has experience hatching emus - perhaps she has some ideas.

Eggs can't gain weight, they can only lose weight, so I'm thinking it's a scale malfunction, or perhaps a typo when taking down the previous weight
