She was a 1 year old hen. No sign of sickness at all. She was big fat and running around. (Except she would drop eggs on the ground and had a lot of soft eggs) This morning I went to feed them and she was laying in the hen house dead with a soft shelled egg right by her. I cut her open and she was filled with very dark red jello like stuff all in her cavity. Also had with bumps like cancer on her intestines. Any clues??
