Goose eggs are a problem. I had a friend 3d print me a goose egg turner for my nuture right. I really wouldn't skimp on a incubator. Hillbilly has good luck with a cheep one but I have not. If you get a nurture right, I will be glad to loan you my goose egg turner. I can mail it to you and you...
They are about 6 inches. I've got the broader netted over but still getting out. They are very easy to catch but I'm worried about access to food and water.
