I have read of older, alpha hens converting to roosters in a rooster-less flock in all aspects except for being able to fertilise eggs. Apparently they crow, protect the flock, grow spurs and rooster feathering etc. This a quote from livescience:
"Sex reversals do, in fact, occur—although not very frequently," states a 2000 report published by the University of Florida's Institute of Food and Agricultural Sciences. "To date, however, spontaneous sex reversalfrom male to female has not been reported."
That's because the mechanics of this biological phenomenon seem to work in only one direction. Normally, female chickens have just one functional ovary, on their left side. Although two sex organs are present during the embryonic stages of all birds, once a chicken's female genes kick in, it typically develops only the left ovary. The right gonad, which has yet to be defined as an ovary, testes, or both (called an ovotestis), typically remains dormant.
Certain medical conditions—such as an ovarian cyst, tumor or diseased adrenal gland—can cause a chicken's left ovary to regress. In the absence of a functional left ovary, the dormant right sex organ may begin to grow, according to Mike Hulet, an associate professor at Penn State University's department of poultry science.
"If the activated right gonad is an ovotestis or testes, it will begin secreting androgens," Hulet told Life's Little Mysteries. Androgens are the class of hormones that are largely responsible for male characteristics and are normally secreted by the testes. "The production of androgen would cause the hen to undergo behavioral changes and make it act more like a rooster."
The hen does not completely change into a rooster, however. This transition is limited to making the bird phenotypically male, meaning that although the hen will develop physical characteristics that will make her look male, she will remain genetically female. So while the hen will no longer lay eggs, she won't be fathering any offspring, either.
Having said that … I have a two and a half year old Bantam Langshan in my rooster-less flock who is not the matriarch but is 2IC. She has never been broody and does not share her food especially meal worms
Just recently, following a hard moult, she decided she was going to crow and she was protecting the flock, breaking up squabbles, calling them over for treats and sharing her meal worms
. She did not go as far as trying to mount them though. The matriarch of the flock was off being a mumma to her 6 weeks old chicks.
Anyways, Dusty’s behaviour was very disconcerting and I was concerned that she may have something going on but, after two weeks of this behaviour, she is back to being a hen .. no crowing, definitely no meal worm sharing and laying eggs the same as she used to pre-moult.
Just my humble opinion based on my experience but with Dusty, I think a combination of the matriarch being otherwise occupied, chicks in the flock and her moulting probably resulted in a hormonal imbalance causing her to be a little gender confused for a while there
The good news … she is back to normal!
