<text>  A hen called Ping Pong laid a one-in-a-billion perfectly round egg - which has now sold on eBay for 480. Owner Kim Broughton, 44, from Latchingdon in Essex, was left shell shocked after her prize Buff Orpington hen laid the spherical egg on Pancake Day. Ms Broughton and Ping Pong decided to auction the egg off on eBay and were amazed when it sold for 480. She is planning to donate the money to the Cystic Fibrosis Trust after a friends son died from the disease. Owner Kim Broughton pictured was left shell shocked after her prize Buff Orpington hen, which has now been re-named Ping Pong, laid the one-in-a-billion perfectly spherical egg last month . The one-in-a-billion round egg right is pictured next to an ordinary slightly pointed egg left Ms Broughton, 44, said she thinks the winning bidder will probably preserve the unusual egg, rather than eat it. The perfectly spherical egg attracted 64 bids during the online auction. Ms Broughton said she had been tempted to cook and eat the egg before being told it was one-in-a-billion. She said: I was literally about to crack it open to make a pancake when a mate saw the photo I put on Facebook and messaged me to say Dont do it! Apparently somebody had sold one before for more than 90 so I thought Great if I can sell if for that. When it was at 20 I thought Whod pay that for an egg? and then it went through the roof - its unbelievable, she told BBC Essex.
