Just went outside to check on our 8, 8 week old chicks who have been out of the coop for the past two hours. As I was walking to the back of the lot, I saw a hawk standing over what appeared to be a chick. As I approached, the hawk flew off. It had killed one of my chicks. Another, a buff laced polish was sitting down by the fence, and not moving at all. I thought she had been killed too. I rushed to the coop to see if any had made it back, I counted 3. I called my wife who came running out...she looked in the coop and thankfully counted 4, and realized that our BLP was actually alive, just "playing dead". We started to search our lot for the missing two, feeling sick about it. We thought they perhaps flew over the 6 foot privacy fence, and were in our neighbors lot. Even though we don't really think they could. Five minutes later, we saw the missing two, in shock, sitting underneath a garbage can waiting for us to arrive and safely get them back to the coop. While we are so thankful 7 of 8 survived (I initially thought only three survived), I am so sickened that this happened to begin with. We were clearly irresponsible for thinking they would be okay in our urban backyard for a few hours.
