I have a SLW/BO pullet between 12-14 weeks old that I found dead this evening when I went to close up, she couldn't have died much before I came down as her neck was still limp and had not stiffened yet. She was on her back just underneath the lowest bar of the roost as though she had been just sitting on the lowest bar, died and fell backwards. Here are the surcumstances, I did not go down to close the coop doors last night because I feel asleep after an extremly long day and did not wake up until this morning. So when I woke up this morning is was snowing/sleeting/raining and it has countinued all day like this so this morning I looked out and I could see all the chickens and everyone seemed alright so I decided not to go down and check on them. I left around 1 and did not get back til 5 and when I went to go and lock the chooks up for the night I found the pullet and I realized the banties (where this pullet was) coop had run out of feed since I'd last checked it (wed. morning). FYI our temps have averaged between 30 - 34 degrees today. So I've figured that she was wet and cold and died of Hypothermia (what are signs of this?). Is there anything I could of done for her? If I came down to check on her earlier all I would have seen is a cold wet chicken just like all of the others what would have distingished her as "near death"? All the other chickens seem just fine if a little wet and cold, how can I prevent this in the future?
