I know it's been discussed to death, but I just don't get it. Let me explain why, and maybe someone can help me understand? I have four chickens that free range most of the time. They have an 84 sq. foot run, with a 24 sq. foot coop, not including a 6' roosting bar and 6 nesting boxes. Everytime I look in the coop, at night time and during the morning when I open their run door, they're using some combination of 3' of roosting bar and 2' or so ON TOP of the nesting boxes. And it's always the same spot. And once they're awake, they head right out of the coop and onto their merry way. I mean, they honestly look like they'd be fine with 2 sq. feet or less per bird. Why do they need that extra space? I'm not looking to add anymore chickens, but I'm wondering if confinement with limited space has some psychological effect on them? Do they go nutty when closed in too much? Are they roaming around in the coop when I'm not watching? Thank you in advance!
