According to your article.
Note: a single hen will occasionally lay an infertile egg. This is a sign that her hormones have gone through the mating season motions in the absence of a male, and is nothing to worry about. The hen will not fret or attempt to incubate the egg. Simply remove it, and that’s that.
I only have the one bird and she most definitely laid an egg and she is attempting to incubate it and won't let me anywhere near it.
