These are the rebar post. They are a triangle metal brace on a 4' piece of rebar. These are the "anchors".
Closeup of the door configuration. It simply wraps around the first post placed & slides over its own rebar post. You can barely see the mesh, so I've highlighted the path in blue & purple.
You can see how easily the top rail slides over the rebar post. The rebar posts are easily bent and mostly snap back into place, taking the top rail along with it, which pulls the mesh tight.
The whole kit & caboodle. Posts are located at the blue arrows. Left forward corner is the door post, so there are two posts there.
With the chickens, waterer, nest box (cut up piece of wood in the center is for privacy while egg laying
the nest box is behind it)
Don't use deer netting. It is too flimsy. But it's working for now while I pay off some stuff on my account at work. I'll get a roll of poultry netting. That will keep it light & moveable, but be more durable than the deer netting. We've already had a couple of tears.
When you plant the rebar posts, angle them away from the center of the square. This will make them pull tighter across the top.
Move ALL your chickeny stuff (waterer, feeder if you use it, nest box, etc) BEFORE you move the pen.
Let your chickens out (if they don't have a shelter inside) about 15 minutes before sundown, or even a bit earlier. I let mine stay in just a bit past sundown and they were already trying to roost. I had to toss them out to make them go to the coop.
I'm thinking about using the same logic to lure them into the coop at night that I use to get them into the pen. Food
I can go out at ten o'clock & rattle a feed bucket and they would come running if they could get out of the coop.
