I have (had) 3 free-ranging hens, but over the last few weeks, I have lost 2. By "lost" I mean that only a few feathers remain! I can't find any evidence of what got to them. We live in Puerto Rico and the predators tend to be feral dogs and cats, mongoose, and hawks. I see no evidence of any of these types of predator. Our chain link, chicken wire enforced fence was slightly bent today, but there is only a 3-4 inch space underneath. Can a chicken get attacked and "escape?" Our property borders jungle and open space on every side except where our house is. What predator grabs an adult hen and takes it somewhere else? This is our first year with chickens, so we are new to the game, but we love it! Our two domestic cats love to visit with the chickens, and our dog is a little too "playful" but we don't see any evidence that she devoured an entire chicken on site!
