Last month, I noticed that Oyster Cracker was not herself. She seemed to be under the weather and not herself. She was almost 6 years old and has had bad days since Sunshine passed almost 6 months ago. The first clue that something was wrong was that she did not roost with the others in her usual spot. She tried to sleep in the nesting box. The next night she ended up on the lower roost where no one sleeps. She was just off. By the next morning, I decided that I needed to do some detective work. So, I set out to figure out just what was wrong. As a chicken keeper, there are lots of things that you can do to help determine what might be wrong with your chicken. I also realized that writing a post on how to examine a chicken might be useful for others.
