I was glad to find this thread. I have an RCom Max 20. Some of my chicken eggs are so big, I can't get 20 eggs in there. So, I'm thinking of getting an additional incubator. I love the ease of the RCom, so I was wondering about the Pro 10. Does it hod temp & humidity as well as the larger units? Here's mine. I had 19 eggs at the start, but removed a few that did not develop.
