My birds are so bored!  I have five 9 week old pullets in a run that's 8x5 (40 square feet, or 8ft per bird) with an upstairs loft (coop) half that size, so 4ft per bird. They can come and go upstairs and downstairs as they please, and there are several different roosting places, so they theoretically have enough space, but they beg me to go out and play and seem very bored inside. (They just sit around most of the time!)  I read to hang up a cabbage, so I did that, but they don't peck or play with it, and I'm not sure what else I can do to entertain them while I'm away at work all day. I let them out in the evening, but they do tend to wander off (luckily my neighbor doesn't seem to mind, though she did call me yesterday to tell me they were visiting her) and I lost one to an unknown chicken thief last week so I want to be careful.
