I used to pick up spent coffee grounds for my compost from Starbucks every week. They kept a bin in their walk in dumpster area and allowed me to take whatever I wanted.
I found this discarded bakery rack and picked it up thinking it might come in handy. I ended up mounting it horizontally as roost bars in my coop.
It’s easy to clean and everyone has their place without getting too close to their neighbours. Best thing is it was totally free.
