Artists and artisans come together at the Faculty of Fine Art to make masks and floats for the Pohela Boishakh procession
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.
