Question comparison to live chicken vs chicken in packaging in grocery store?

Question

when you lift up a live chicken, its light as a feather......but when you hold a butchered chicken with its head and legs and feathurs and guts taken out in a grocery store.......its heavyer then a live chicken, why?

Answer 1

A live chicken is less dense, since the feathers occupy volume but add little mass.  It looks bigger.  But I assure you, the same chicken is heavier before butchering than after.  You just happened to pick a light live chicken and a heavy butchered chicken.  Also, your perception of weight is affected by what you expect.  A one-pound bowling ball will feel lighter than a one-pound head of lettuce.

Answer 2

That's a tough one because when the feathers are yanked off, the head is chopped off, it's disemboweled, feet chopped  off, and bleeds all over the place, the chicken has lost a significant amount of body mass. I gotta figure the chicken feels lighter.

Perhaps it's that what weighs more a pound of feathers or a pound of butchered chicken thing.
