It's rare but it does happen. Hens are born with two ovaries but one of them always atrophies so that there's only one functional ovary in a normal hen. If this ovary is damaged the symptoms I described earlier will occur. I've had it happen with three of my hens in the past and needless to say the first time it happened I was astounded. A hen crowing is just disturbing until you know what's going on.Wow, that's interesting! I never knew that it could happen![]()
That said, it's still very possible the hen in this case was just making weird, new noises and will turn out to be otherwise normal.
