A shopper was left surprised after a quail egg she bought from Waitrose hatched.
Surrey woman Mandy Clayton, 49, said one of the eggs that didn't make it into her salad ended up as a family pet called Rose.
Mother-of-six Mrs Clayton said: "I'd bought a dozen quails' eggs for a barbecue, and had four left over from the salad, so I just put them in the incubator to see what would happen.
"I know they were free range eggs, but I really didn’t expect one to hatch. It was in there 16 days in all."
Waitrose said the strong trading period was driven by growth in online groceries sales, which rose by more than a third in the five weeks to Christmas Eve compared with the same period in 2012.
It said that 619,000 people used their click and collect service in the same five-week period.
Waitrose says it has seen its most successful Christmas on record after sales for the twelve trading days up to December 31 were up 6.5% on last year.
Total sales for the five weeks up to Christmas Eve was 5.4% above the same period in 2012.
It said it also recorded its most successful single day of trading ever after taking £51m on Monday December 23.
John Lewis and Waitrose staff are set for bonuses worth 15 percent of their salaries tomorrow as the retail chain marks a rise in profits.
John Lewis Partnership, which is owned by its 84,700 employees, cut its staff bonus from 18% to 14% last year after it suffered a 4% fall in profits to £353.8 million.
But staff are poised to get a "small increase" in their latest bonuses thanks to a 17% hike in profits after a "bumper" Christmas, said retail analyst Nick Bubb.
The same percentage bonus is received by each worker in the company, from check-out assistants to chairman Charlie Mayfield.
Pippa Middleton said she was "delighted" to become a columnist for Waitrose's monthly magazine.
The Duchess of Cambridge's sister will pen a column called Pippa's Friday Night Feasts which will feature "casual dining ideas and recipes".
The first column will appear in the April edition, with Pippa featuring on the front cover.
Miss Middleton said: "I'm delighted to be writing for Waitrose Kitchen, a magazine that's always been a source of inspiration to me, for its extensive spectrum of food and beautiful style.
"My column, 'Pippa's Friday Night Feasts' will be an exciting opportunity to share my own passion and enthusiasm for food and entertaining and I can't wait to get started."
