I let my girls out of the coop to do what chickens do....hang out in our garden and scratch around in the woods. I get a knock in the door about an hour later....one of my neighbors ask if I had lost a chicken.....apparently, one of my bantam girls hopped the 5 ft fence, crossed the road, and was hunkered in my neighbors garden. After retrieving her, my immediate fear was, where was everyone else? Come to find out my neighbor's dog got out, and you know the rest. One of my girls was injured; punctures on one wing, but not on the body. My neighbor girl found her on the other side of the creek, wet and injured. One by one, the rest of my girls came home (to the shake of the treat jar), except one. Greta has always been the most skittish, not even attracted to the lure of a treat, always on guard. She hasn't made it back by nightfall. I'm not sure if she was taken out (but the solo dog was already chewing on my poor Rosie), sitting under someone's deck, or has traveled so far that she can't find her way back. My girls only free range for a few hours of the day and they don't go far. If Greta wanted to find her way home, would she call to her flock if she was lost?
