A chicken belonging to a Gloucestershire man has laid an egg double the normal size.
Jeremy Power, from Cheltenham, said his hen Rainbow produced the egg on Saturday.
"Sadly it's not a world record, ours comes in at about 130g (4.6oz) whereas there are eggs on record of 160g (5.6oz), " he said.
"It's all a bit of a dodgy world really in that there's no one to actually authenticate the weight of an egg."
The average egg weighs about 56.7g (2oz).
'Poor little chicken'
Mr Power said: "We've only got two chickens and every so often you do get an egg which is bigger than a normal egg but this one really has caught us by surprise.
"On Saturday, Rainbow really was on top form. I opened up the chicken house and there was this enormous egg. It's almost like a comedy egg it was so big.
"Ouch, that is everyone's reaction to it... poor little chicken."
He said he was intrigued what was inside it.
"On YouTube there is video - which I don't think is a fake - of an egg that size being opened up and inside is another egg.
"The question is what is inside our egg. I think I'll have to video us opening it up just in case there's a surprise in there."
A spokesman for Guinness World Records said: "The heaviest egg reported to have been laid by a hen is one of 454g (16oz), with a double yolk and double shell, laid by a White Leghorn at Vineland, New Jersey, USA, on 25 February 1956."
