Well we woke up this morning to find our second dead chicken. The first was a few months ago and she was wheezing. Some thought it was pneumonia. Nothing else happened for sometime. Everyone was happy and healthy. Last night my wife noticed the one buff looking tired. She could hardly keep her eyes open sitting on the roost. I just thought she must be tired and enjoying the dip in temperature. Her comb was pale in color but didn't look bad. Her legs were a light yellow color. I thought she was just not laying. She is 2 1/2 years old. No wheezing, No sneezing, No cough, and eating the morning before (vegies). Was she just old? Or am I missing something. I have not wormed the chickens. Maybe she has worms and became anemic?
