No one said the hen actually changes into a rooster. But to most people, if it suddenly stops laying eggs and starts looking and acting like a rooster, they will just think that and call it one. So they can “change.” Obviously not literally but looking and acting like one which is kind of the same thing for people who can’t keep roos. Also I just skimmed that article and idk if you read it or not but if you do, it literally mentions all the science and everything you said about the left ovary and how the hen does NOT actually become a rooster. So it’s not trying to deceive anyone and not click bait or anything. It explains all the details really well.
