I am new to chicken keeping. Our coop will be built on a hill that is pretty barren. I'm planning on using electric wire fence around about an acre to keep out most ground predators. I've seeded part of it with clovers and grasses for foraging, and have a large number of blackberry seedlings that I bought from the state conservation department for pretty cheap, and will plant several of those in the chicken pen.
I'm thinking of making a teepee or two from leftover pole bean seeds for a shelter?? I also have sunflower seeds that I bought to shade the coop, which is raised 18 inches off the ground as an additional shelter. I have an igloo doghouse that I found on the curb that my dog never used but maybe the chickens will?
I really love this picture of a chicken gazebo that we could build from fallen wood:
And I saw very simple ideas here:

I also bought some reflective tape that I am planning on putting strips on cheap wooden stakes to make "flags" around the area.
It really sounds like anything the chickens can hide under or that disrupts the hawk/eagle from being able to make a dive will help deter.
