She was fine yesterday morning. Last night I noticed something was off. She ate her dinner on her side. I brought her in and gave her a bath so I could really look her over. She's stumbling when walking. Here are the facts: 1) her flock has an enclosed potion of the yard to roam. It is possible that something got her. But I checked her out and there are no visible wounds or missing feather patches 2) vent is clear 3) crop is hard. I'll check it again in the morning. 4) she has an appetite. 5) she is really dirty 6) she was dewormed three weeks ago as a precaution.
