I went outside a bit ago and found one of my black Australorp hens, about 3 months old, lying in the pen and being walked on by the others (because she was lying near the food). She had her neck bent at a really odd angle and I at first thought she was dead. She was not panting, but she would only move slightly when the others walked all over her to get to the feeder because the knew what was coming. I picked her up and carried her inside, and she never attempted to move. I put her in the brooder box which still had bedding in from the last chicks who recently moved out. It is in the basement and had not been heated, so it was nice and cool. Within a few minutes, she sat up but did not stand. I offered her food and water and she ate a good bit and drank some, too. She is now slightly standing, slightly squatting. Her neck is fine and she moves it in all directions well. However, she is so puffed up (feathers) that it looks as if she has no neck. Her wings appear to be hanging a little low, but I think they are a little better than when I first brought her in. Her crop feels empty (well, it did before she ate) if I am checking correctly. I can't tell that anything else is wrong. I thought maybe dehydration because it is very hot here today, but the others are fine... No one was panting and they all seemed completely normal except for her. She is not moving, just standing in one place now that she's up off her side. She seemed fine yesterday. Have not seen any poop. If she's pooped, it's covered up in the bedding and I've missed it... I can't help but think heat since she got up so soon after I brought her in. But their pen is completely shaded and it's probably only in the 80's in there... Any ideas?
