Can Roosters turn into Hens? pics

Please direct me to a source for information that supports this. A hen can't "turn into a rooster". A hen may become dominate in the absence of a male. A hen, because of disease, may develop male feather or comb characteristics, but a hen can not grow testes & become male.
If you can direct me to valid scientific information to the contrary I'll eat my hat.

Man...I'd almost pay to see that!

Sorry, couldn't resist.

Does this count?

Both of the last 2 posts refer to experimental manipulation of an embryo, not the spontaneous action of an adult changing gender. I think my hat is still safe.

Thanks for the links Tim very interesting info you passed along, now I don't feel so hung out and dried

some(s) answers sometimes turn into more of a ques. or cut and dry, blunt/short. EDIT anyway thanks Tim for "elaborating" well making it easier for the average ol' Joe to get there from here

chickens can change sex ive had classes on poultry and there are cases where the chicken has both parts and at some point one will take over and it can be a hen at first or a rooster then either the testicles or ovaries can deteriorate and the outward appearance can change. the bird is essentially a hermaphrodite

I don't think so.
Neither case involving chickens resulted in a hen developing testes or a cock developing ovaries. I said physical appearance may change as a result of hormone imbalance but actual gender does not change. The articles cited say the same thing.
Here are quotes from those articles.

Genetically, the bird remains a
female, but externally it appears male.



The ovary appeared somewhat tumified, and attached to it were two
yellowish, rounded bodies; one the size of a hazel nut, the other the size of a
corn kernel. The oviduct was intact, although somewhat smaller than in an
actively laying hen. The shell gland was plainly discernible

The artice concerning the Cardinal speaks only of plumage, an external characteristic. I suspect had that bird been disected it too would have remained genetically female.​

A female that is able to fertilize other females is pretty much "male" in my book.

Did I miss something? Where did you see evidence of this happening?

Wow! Learn something new everyday!!! (I found out a year ago that this can happen with my "Nemo" clownfish!!!)

quote: "In general, spontaneous sex reversal has been
described as the result of pathological conditions
(e.g., ovarian cyst or tumor, diseased adrenal glands)
which cause the left ovary to regress. Residual tissue
in the right ovary proliferates in the absence of a
functional left ovary. This regenerated right gonad is
known as an ovotestis and may contain tissue
characterisitics of the ovary, the testes, or both.
There are reports of these ovotestes producing semen
capable of fathering offspring. Most, however, will
never lay an egg or sire offspring."
