The reason I use chicken wire is because it comes in 5 or 6 foot high rolls, which makes it much easier to set up a run. 3 foot high hardware mesh is inconvenient to work with in a large run, as you would need to build it out of wood to staple the mesh to halfway up your 6 foot fence.
I care about my chickens, as everybody should. The original intent for this thread was to tell everyone what I personally thought about the chicken wire I buy. If I didn't care about my chickens, I wouldn't own them.
Haha! You never know, my angry steer is unpredictable with what he eats.
