An assistant professor in design at Iowa State University, Austin Stewart, has released ideas for a project named “Second Livestock” which involves tricking chickens into thinking that they are free range, while they are actually contained within small enclosures. This would be achieved by strapping virtual reality headsets onto farmed chickens (stop laughing). These “Cockulus Rift” headsets would therefore make the chickens believe that they are in a nicer, less stressful environment (really, try to stop laughing).
