This morning I found one of my chickens and my alpha rooster on the ground of their chicken coop! I tried finding out what could have happened to them but I couldn't figure it out. There were no sign or symptoms pointing to sickness- the day before they were cheerful as ever and they hadn't lost any weight. So I tried looking for clues if any foul play was involved, but I couldn't find a scratch on them, no feathers plucked out, nothing. They showed no signs of poisoning either; as there face remained red and plump, and they ate sparingly. So I am completely stumped at this point. The only unusual thing is that their bodies are overwhelmingly stiff, which I've seen occur in poisoning- but again they had color on their faces. I'm really hoping you guys can help me out, any information is greatly appreciated. Thanks in advanced for all the comments, advise, info, and for your time. Useful Info: Where I live the days have been hot, but has breezy afternoons. Our home is surrounded by nature, many animals come to visit such as ground squirrels, cranes, owls, hawks, mice, a skunk recently, and many other animals. They always have sufficient food a mix of scratch, mash, black oil sunflower seeds, and the occasional bugs they'd find and fruit from our trees. Our chickens are free-range and had 24 in all, all different ages.
