Chicken tunnel

[Harry4802]

I had that but made the wire fence in a upside down U, garden staples to hold it in also. 12-14" wide at the bottom and about a foot tall. Inside I had pavers so the area didn't get muddy. They learned it Super fast.
It went from the Run to the front yard, about 15-20 feet long. At the run to tunnel I had a wood plank to close off the tunnel and a cinder block to make sure it didn't move.

You have to make sure it is TALL enough and it is better to have it 2 Hen wide.... they like to run in to see who can get in/out first.

Yes a piece of wood sounds good to close it off. I am going to try this. Thanks
