Meet Gertie, the F2M trans chicken. When Gertie’s egg-laying slowed to a crawl this winter, Jeanette and Jim Howard didn’t think all that much of it. But when their hen developed wattles and her comb began to grow, the couple took notice. When she began crowing, something only males are capable of, the Howards were downright shocked.

BBC reports:

Cambridge veterinary surgeon, Marion Ford, told the BBC that an apparent sex change in hens was not uncommon.

She said that it could be caused by mycotoxins or fungi that can develop when animal feed is stored, and these have the same effect as synthetic hormones.

“An increase in testosterone will result in a hen growing an extended comb, exaggerated wattles, and cockerel-like behaviour including strutting and crowing,” explained Mrs Ford.

Mrs Howard said: “I’m not really sure whether Gertie has actually changed sex, but to all intents and purposes she’s now a cockerel.”

It is not known whether the effects of the mycotoxins are reversible.

Kind of brings new meaning to the word cock-a-doodle-do, doesn’t it?
