I have 2 emu eggs in the incubator, and I haven't heard any peeping or seen any wiggling from them at all. They were due to hatch on the 15th. How long should I wait before I crack em open and see what went wrong?
I don't know the answer to your question, but do find it interesting. I tried to find something on the internet, but didn't come up with a definite answer. I did however find this document, which I thought could be helpful in diagnosing what might have gone wrong. Table 3 list several possible causes. Table 1 shows the incubation time to hatch for Emu eggs, which I image you already know. I would be interested in hearing about your outcome. One day, I might try to do this myself.
