My boy IS DOING IT RIGHT and has been all along. I AM getting fertilized eggs and have been all this time that I've been calling him names, threatening to throw him in a pot, and suspecting him of being gay. Mea culpa! Mea culpa! Mea Culpa! Miss Prissy was right. I was looking at the spot on the yolk wrong, thinking that the "donut" proof of fertilized eggs should be bigger, like at least a very obvious fourth-of-an-inch ring. I was just now reading another post and opened this URL, https://www.backyardchickens.com/forum/viewtopic.php?id=16008 , that shows a MUCH smaller, less conspicuous donut, much unlike the one I saw on another post several months ago. Miss Prissy, bless her little pointed head, told me last week that she suspected that I didn't know what I was looking for, and SHE WAS RIGHT.
