Our favorite hen died this morning and we do not have a clue as to why. All the others are fine. She had not layed for nearly a mt and had lost weight. Being new to this we read all we could but there are som many things that could have happened. She was very thin. I had taken her and isolated her with a light for warmth but she died a few mins later. We have only 5 hens and a rooster. We are fairly new to owning and raising chickens. Have no idea what happened.
