I just brought home 26 hens to start raising chickens. They were hatched on 8-11-10. On the 3rd day in their new coop/cage, morning inspection showed two small holes where someone/something tried to tunnel into their pen. I thought my pen was bullet proofed for illegal entry. I used 1" X 1/2" welded screening, thinking no real/normal predator could crawl through such a small hole, I proceeded into the coop for cleaning/feeding. As I reached into the feed barrel, a quick unexpected movement nearby caught my attention. I sent all my chicks outside, & proceeded to apprehend the intruder. What a shock to find a small "rabbit" had squirmed his way into the pen/coop!! One feed bowl was completely empty. Bugs Bunny must have had a very full tummy. When last seen, he was doing about 130 mph across the acreage, w/a dust cloud trailing behind. Can a small rabbit be classified as a predator or a trespasser?
