Ordinary-looking hen with brown feathers has become a celebrity in Cuautitlan, a small village north of Mexico City, because every day she lays an egg with a green shell.
At first glance, Rabanita looks no different from the other chickens in the yard.
"Since the December 5 she has been laying green eggs," said her owner, Elvira Romero.
Romero is a housewife who got the hen as part of a government aid package to help villagers.
"Well, my children say 'Oh Mummy, God looks favourably on you so that you were given as a prize a chicken that lays green eggs'," said Romero with a smile.
So far, there is no explanation for the colour of the eggs.
Romero says that Rabanita does not have a special diet different from the rest of the chickens, just the usual corn, tortillas and chicken feed.
Scientists believe that shell colour - which does not affect the colour or flavour of the yolk or white - is determined by the genes, and say blue or green shells are frequently found in the Araucana chicken strain.
Green egg layers attract a premium in some parts of South America, where poultry breeders aim to produce chickens, which lay nothing else.
