Junglegym for chickens?

[FiveHens]

I would say: variety in the run/coop (ie: leftover food and other goodies, weeds and raked leaves thrown in for exploration/pecking purposes)
Also: dust for dust baths, chicken-resistant greenery (if it exists), bushes, maybe stumps, rocks, etc: just a variety so it's not just same old, same old.

I like the tether cabbage pics!

mine like a flake of straw, I pitch one in their run every few weeks, and they go insane! Also, for baby chicks, I put a shovel full of dirt with the grass on top, right in the pen. they play king of the mountain, and eat the tiny bugs and practice scratching.. also provides free grit
