I added an outside daytime area under a tree for the chickens. It's the closest I can come to free ranging, for various reasons. Mainly because we have many kinds of hawks (saw a Cooper's dive bombing something in the yard behind me), and bald eagles. Year round. I lost a chick at one week to a very sneaky Cooper's hawk when I was 20' away, even though their little area was covered (there was a 10" gap that I didn't know about, but the hawk did).
As I only have 4 hens, a loss would be a 25% decrease, and I'm not currently in the mood to integrate new chickens, though I will have to down the road.
So, the coop and secure run are 6x10', with another area behind and next to the greenhouse netted over for daytime.
The run under the tree is the third area, connected to the coop via a chicken tunnel.
I have wide nylon straps around the tree (to minimize damage), to connect the coated wire to. There are 'turnbuckles' on the fence post end so that the wire can be tightened if needed. I used poultry netting over the top.
The sides are plastic deer netting. The posts are 'U' metal posts.
There are some grazing frames for the chickens inside this run.
This run extends along the fence to the right so they can forage for bugs in the bushes.
View of the greenhouse and coop, chicken tunnel is hard to see but runs in front of them.
Anyway, this might give someone ideas if they have some limitations for free ranging.
