I know this is a local pest here in Hawaii, but Iʻm sure some of you have ferrets that attack your chickens too and I need all the help I can get. I have been losing at least a bird per night, sometimes as many as four, to a unknown predator. Since it never gets below 60 degrees, the chickens are kept in a 10ʻ x 10ʻ shade house with a solid tarp as a roof. After the first raid, I put a 3ʻ high fence of 2" hardware cloth all around it. After the second raid, I put 4ʻ high chicken wire over the hardware cloth and tied the entire thing to the structure so nothing could get in or out. Yet. we continue to lose birds. No digging around the perimeter, no holes in the fencing, no signs of forced entry at all. Its bad enough when we find a carcass chewed up and headless, but often when we count, a chicken is just gone! No body parts in the pen, no feathers strewn around, nothing! It had to be dragged out, but how? I think I need CCSI - Chicken Crime Scene Investigators. Help!!!
