I tried to listen with my stethoscope to see if my two little (big actually) emu eggs were alive. I heard nothing as usual. But I noticed that one side of the eggs is cool after being out of the incubator for a few minutes. The other end of the eggs is still warm. I thought it was just me... They felt like that because I want them to. But I was holding them on their sides so it wasn't my hand keeping the ends warm. And it was a definite difference in temperature. No mistaking it. I'm so excited! I will say that I thought it was too early for them to generate their own heat though.
