I have (had) 2 chickens and 2 evenings ago as I was putting them inside one of them seemed to be wretching and stretching her neck up and down, she then vomited a bit she did not want to go inside so I left them out side for the night as it was nice and warm, when I went to them in the morning the poorly one had fallen asleep outside I picked her up and took her inside the house, she was extremely sleepy I left her with my daughter as I had to go to work. Dd felt she may be egg bound so put her in a warm bath oiled her vent and finally tried to extract the egg but there was nothing but pooh up there. She kept her on her knee wrapped in a towel and eventually she let out a long cry and died.:( All that said, does anyone know what could have been wrong with her as I am worried it was a disease and worry that the other one will go the same way.
