Yesterday, our oldest chicken passed away. There were no injuries, and there was nothing wrong with her. Today, I found her daughter had died. Again, no injuries, and it look like she just layed down and died. The mother was 8, and the daughter was 7, so they were getting up there in age. She was near the bottom of the pecking order and followed mom around all the time. The other guys look fine, no weight loss, all eating good, and no pale combs or puffed up birds. I have 2 more of her daughters, but they both are fine.
