LOL! You have to wonder about your magic neighbor! This is only our 3rd year with chickens. After the raccoon killing, two of our lovely ladies (Rosie and Bella) were free ranging during the day in the back open area near our house. We had always allowed the girls to free range when we were home during the day and had never experienced negative consequences. They used to follow us along with the dog and the cat on walks through the woods. That day, I was napping and heard a couple of loud squawks. The dog was with me and she didn't react so I thought it was just the girls fussing at each other. About an hour later, my husband was in the back and called for me to look at a couple of piles of feathers. We couldn't find Rosie or Bella. Then we found them both beheaded in the woods. We later determined that it was a pair of red tailed hawks that came hunting through. The hens proved to be too heavy for them to carry intact back to their nests. It was spring and we understand that they hunt to feed their hatched young more aggressively during this time of year. The hawks came back a week later when we were watching over our hens ranging in the meadow and RIGHT IN FRONT OF US AND THE DOG, swooped down an tried to pick off two more of them.
Now we no longer alllow them to free range. In addition to our secure run, we have a hatch leading to a 1200 sq ft fenced area covered with trees and bushes where they can range during the day. We are in process of placing slender roping at 3 ft intervals over the top of that area as an extra precaution against swooping predators.
All in all, we are happy with our set up now although I miss the "herd" of hens racing down the driveway when I exit our house.
