I have had problems with the Hawks Killing my chickens. I had lost many beautiful baby chicks. Then I decided to build a walk in coop.Made a frame with the 4X4 s and 2x4 s and spread this netting all around.I am very happy. it is small openings compare to the one I had before (it was 1x1 inch) and a lot of little birds caught in it.It is also very strong, UV treated.I will know in few years if it holds up to the sun.
