Don't worry, Ron Mueck's Still Life is not an actual chicken being hung from the ceiling.
Ron Mueck is known for making hyperreal sculptures that makes you look in awe as you debate whether or not his work is real. The display called Still Life depicts a large chicken skinned and hung upside down in the middle of the museum. It's almost like staring at a public execution for the poor animal. As morbid as it may be, this is one display you can't turn away from.
