She had been lethargic for days so I knew she was not feeling well. When a cockerel jumped her and she just laid on her side after I scared him off her I knew she was in trouble. She had a very high heart rate and high, labored breathing rate. She kept her eyes closed and after a few gasps for air she gave up and died. I wonder if anyone has any ideas what could have caused her death. She was never old enough to lay any eggs, maybe about five or six months old. Upon dying she pooped bright yellow liquid poop but I had not noticed anything odd about her poop up until her death.
