Every night right after it gets dark I close the door to the chicken coop after all the chickens go in. I counted them and realized one was missing. After looking around I found her laying on the ground with her head in the dirt under the water bowl. Anyone know what might have caused her to die so suddenly? That morning she pooped a clear fluid. Not sure if that had anything to do with it. I just want to make that what she had won't spread. Please reply if you have any suggestions on what might have caused this.
