Thank you all. This are all great and helpful answers. Yes, we have a house cat and she had been on our kitchen counter knocking the egg off and then eating.
We will keep reading up before we do our first try.
We have been looking into incubating eggs and reading up on it. We bought 2 incubators (Nuture Right 360 and Brinsea Maxi 24 Advance). The second one is a backup in case something happens to the other and also avoiding the cheap ones. We also got a candler and a hydrometer too as it is...
