French artist Abraham Poincheval, who famously spent a week inside a rock and two weeks inside a bear sculpture, has succeeded in hatching chicken eggs after incubating them for some three weeks. Poincheval embarked on his latest project in late March of imitating a mother hen by incubating some 10 eggs with his own body heat inside a glass vivarium at Paris’ Palais de Tokyo contemporary art museum. At the time, he estimated it would take 21-26 days for the eggs to hatch and the first did so on Tuesday. A spokeswoman for the museum said on Thursday nine had hatched and the chicks were on their way to a farm. For the endeavour, Poincheval sat on a chair, wrapped in an insulating blanket, over a container with the eggs. He could leave his seat for no more than 30 minutes a day for meals. Earlier this year, the artist spent a week inside a block of stone, while in 2014, he lived in a hollowed-out bear sculpture for two weeks. The Palais de Tokyo is a building dedicated to modern and contemporary art, located at 13 avenue du Président-Wilson, near the Trocadéro, in the 16th arrondissement of Paris. The eastern wing of the building belongs to the City of Paris, and hosts the Musée d’Art Moderne de la Ville de Paris.
