The small egg is a normal duck egg. I found it in the duck house this morning. My turkey lives with the ducks so could it be from her? (I know that it isn't advisable to put a turkey in with ducks but she is best friends with a young muscovey and we currently don't have any companions of her own kind just now.) I thought Turkey eggs would be speckled, but I did clean it and maybe wiped the speckles off? It isn't a goose egg as they live in another house. Any ideas?
