I came home this afternoon to find roughly a dozen black poops. I mean really black, but not runny. I looked around and everyone was making with the crazy just like normal. I spent nearly and hour and a half checking the internet and my chicken books, then it dawned on me-- blueberries. I fed them a handful of blueberries with their morning yoghurt (no they aren't spoiled). In short, my chickens are healthy but I'm hypertensive!
