A family are auctioning off an extremely rare, completely round egg laid by one of their hens.

Kim Broughton, of Latchingdon, was going to make a pancake with the egg until a friend on Facebook told her how one man had sold his perfectly round egg on ebay for £91.

Her daughter Elizabeth has since put yesterday's egg on ebay to raise money for the Cystic Fibrosis Trust.

Shell-shocked housewife Mrs Broughton, who has 15 hens, said: “I was very surprised when I found the egg .

“It’s quite amazing to see."

To make a bid on ebay, search round chicken egg.
