Best method to mount cages in a barn - hanging, shelving brackets?

[Harbisgirl]

I'll be installing 4 cages in my barn. One level, so waste can drop to the ground. What is the best method? Hanging? Shelving brackets? I think I would prefer to hang them, so there isn't anything below to accumulate poop/pee. But I want it to be sturdy and stationary.

My favorite way to hang cages is from above (no solid parts underneath to collect poo/hay/hair). My husband used pipes across the top and bottom of the wire cages to distribute the weight so the cages are deformed. Here's more, including a link to another post that has photos:
