I've had chickens about 9 months, and none of them have ever been inclined to try to make it over my 6 foot fence. Yesterday my neighbor came by and asked if I was missing a black chicken. "WHAAAAT?!" said I. Sure enough, my Australorp had high-tailed it to the other side of the fence! I couldn't leave the kids alone to go down and around the street to her house, so I had to wait until my husband got home, and by then it was dark. I still went looking for her, bawking around my neighbor's yard, calling for her. My neighbor must've thought I was a class-A nut. I didn't find her, so I had to go home chicken-less. I worried all night that something had gotten her, or that she had gotten well and truly lost. This morning I took the kids to school and went back to my neighbor's house to try again. And wah-lah, there was my black hen, sitting on the AC, letting the warm air blow on her butt! I was so happy to see her. I picked her up, plunked her in the passenger seat and away we went! She was very perturbed by riding in a car. But the fun part was yet to come. We're having our floors replaced, so I got to stoically walk through my house to the backyard carrying a chicken, much to the surprise of the nice fellows doing my floors. I offered no explanation, and they did not ask for one. *sniff* That's right, I have pet chickens. I am not ashamed ... The silly bird in question ... back in her coop!
