This one is store bought from TSC and says it’s good for 4-6 hens. My hubby built the new coop and it’s 6’ X 8’ (I think) and I wanted to be able to walk in it AND give them plenty of shade from our brutal summers.
It's an old hubcap...just something for them to play with. I have a few hanging on the fence in the yard too...they seem to like pecking at it and maybe seeing their reflection in it?
