I think it's a chicken trap that many predators would love to enter, sorry.
Also, there's no shade or water available, and it's way too small for it's intended purpose.
For ground predators, electric fencing, either electrified poultry netting, or multiple lines of electric wire or rope, would be better.
For raptors, keeping them inside a covered area for two or three weeks makes a difference, after an attack. The hawk most likely will give up and move on elsewhere.
Having sheltered places for them to hide under helps too; pallets on blocks, shrubbery, bird netting overhead, all useful.
@Howard E ,
@cmom , and Premier1supplies.com are good resources for ideas about this.
A movable hoop coop works pretty well too, and
@aart has photos of her run that are impressive, complete with lurking hawk!
