To test out her new incubator, Fiona Bottema from Yde, Drenthe decided to run an experiment to find out whether supermarket eggs are really unfertilized. She bought 24 quail eggs from Albert Heijn, put them in an incubator, and about two weeks later she is now the proud owner of six quail chicks, she writes on Facebook.
Bottema bought the box of 24 eggs early in February. Before she put them in the incubator, she first did the so-called float test - put the eggs in warm water to see if they float. Five egs moved around in the water, indicating life.
