You mean live a normal natural farm style life? There has been no evidence presented of worm/lice infestations, sour crop or Bumblefoot. And video of mice running in a park area near a stream is not unusual. This sounds like someone who has an axe to grind with the museum. Which to me, lessens...
Sounds like some one forgot that Chickens are "live stock" and not pets. These chickens get to live out their normal life span so this is an oasis for them.
