Ordered both Sebastopol Goose eggs and Shetland Goose eggs to incubate and came up empty. I gave them time to develop, saw no veins, finally opened them up to see unfertilized eggs from appearance. One offered to send more eggs if I paid the freight. I had just used the incubator to hatch call ducks and had a successful hatch, so I know it wasn't my incubator. I've ordered and had a few unfertilized before, but never all of them. Please be careful who you order from.
