I got this little hen as an adult from a feed store that a breeder every so often takes some of his birds to. She had been dropped off less then 30 minutes before I bought her (she came with a Roo, but I have too many already and don't need another).
From her behavior it is apparent that she has spent alot of time in small cages and had never seen a perch before (looked at one in puzzlement). She is also not fazed by strange sights and smells (car engines, dogs, cats, loud noises, etc.). I opened a garbage bag with her perched on my shoulder and she didn't even blink. So I think she has led an active life doing something, just not sure what.
Here are the best pics of her that I could get.
