A SEX change chicken which began life as an egg-laying hen has turned into a crowing cock.
Stunned owner Jeanette Howard, 79, couldn't believe her eyes or ears when one-year-old Gertie sprouted a distinctive red comb and chin wattle — and started crowing at dawn.
Now she plans to re-name Gertie, Bertie.
Mrs Howard said she first noticed something was up with Gertie when she started to walk differently from her other two hens, Daisy and Gracie.
She has since been reassured by vets that the hen is fine — but that damage to her ovaries could have caused Gertie to develop male characteristics.
