I would love have one of these traps. Is there any one that would like to split the shipping? The shipping is the same for one or two.I have a large covered run that is filled with wood chip (used to be the kids playground). I have hardware cloth that prevents rodents from getting under the coop (as it can be seen behind the blue Jersey Giant pullet in CL's 3rd photo). The cloth bends out at a right angle under the wood chip to form a skirt. My coop is 10"x12" and the run is twice that size. I scoop the poop from the coop and put it in the compost pile; I don't put it in the run. My run does not get too messy except for molted feathers because my chickens free-range all day. They were stuck in the run for 2 weeks this summer while we were in Hawaii, but therun did not get very bad. I occasionally do take a wheelbarrow in there and scoop out the worst of it, but I do this at most once a year. They do hang out there for a month or so at a time when the yard is filled with snow. I hardly had a problem with flies at all this summer. I think it is because the HS kid I hired to care for the birds while I was in Hawaii confused the permethrin dust with the DE, and had quite a heavy layer of permethrin throughout the coop and run. I also hve dust baths in the run with permethrin and DE in them. The other summer I put out Rid-Max Fly Traps. They are non-chemical, reusable traps I hang them with piece of cardboard about an inch underneath. I slide a plastic lid with some stinky food or animal poop onto the cardboard directly under the trap. Flies fly in but can't get out. The trap fills, flies die and dry out. I throw the dessicated flies into the yard and the chickens all come running over to eat them.
