Opinions on the drive in dig barriers.. do they work?

[Artscape68]

I just ordered some of those no dig barriers that you drive in the ground like this. Has anyone used these? I am doing it for a smaller run/chicken tractor that I can move around. I have hardware cloth around my big coop.

I just put boards around the bottom of my run. I have 4 dogs and there are foxes that come around but the boards work just fine

I have some boards blocking in my main coop. I want something that I can move/adjust if I move the chicken tractor
