Hi I have an emu egg and its 38 days old. It has not been making any noises or moving but when I tap on the egg, it sounds like a tink tink. It sounds like if the egg was hollow inside. Sounds similar to tapping on glass but a higher pitch sound. The egg used to smell like rotten eggs but I changed the water for the humidity and I mixed it with hydrogen peroxide and it doesn't smell anymore. I also did the cool down test and I let it get to room temperature but only one side feels a tiny bit warmer, almost nothing. Should I wait longer to test it again? When should I make a safety hole to allow oxygen to enter the egg? What does it mean if the egg is in this condition? Thank You!
