but I cant find any evidence. The coop is about 30' from my bedroom window. Several times I heard what I can only describe as a loud "chewing" or "scratching" noise coming from the vicinity of the coop and a couple of soft thumps, followed by some clucking & chirping from the chickens. I went out with a flashlight and my black lab (whose second favorite activity is chasing the "chippies"). I never saw anything, or evidence of anything, but one time she went absolutely ballistic trying to get at something under the compost pile and ended up flushing whatever it was into the woods. In the end, I wound up closing the chicken door (which is usually open to their completely enclosed run) and barricading the main door with a 5g bucket of water and a large, heavy pallet. Of course- now I'm worried that all the predator proofing I did while building the coop isnt going to be good enough.
