Easy, free wall liner that chickens won't eat?

[Alaskan]

Here in Minnesota at menards a 4'x8' sheet of 1/4" osb is $10.14

Wow.....well, no such luck for me.

Lots of extra transportation to get it to Alaska.

And I live in a small town, but at least my town as road access....

Woven plastic feed sacks. Remove the string at top and bottom, Cut the bag open. Now you have several square feet of tough plastic wall paper. Put the printed side out for a colorful touch or printed side in for a white interior.

Not to disagree with emrys:

I was using feed bags for my poop board liner.

Found single ply they scratched and peck holes in them in my application.

On the walls could be entirely different I have have to admit probably worth a try.

Double ply worked best for my particular birds and needs.

I have golden Comet full size hens.
