Can confinement make chickens aggressive?
Inversely, can free-ranging make chickens less aggressive?
Picture this scenario, let's say you have a flock of RIR's, if you let them free-range would they be less aggressive vs. cooping them up? This is an otherwise "bossy" breed, I'm wondering if free-ranging makes chickens somewhat happier and more easy-going compared to being cooped up.
Examples from personal experiences are very welcome.
