I have a bit of a problem, I seem to have attracted every fly in the area. I have a section in my yard about 300 square feet that belongs to my 8 chickens. I clean the coop every morning and pick up poop in the yard every afternoon. i also rake up the bits I cant get. I have a blue light/bug zapper thing that does nothing! and sometimes I even spray flying insect killer. Adjacent to my chickens on the other side of the wall is my neighbor, who has been complaning about the flies. We live in an Urban area but chickens are allowed. I have also tried hanging those bags that you put water in and smell like a dead body, that is what brought in the big flies. Im not sure what to do. HELP!
