Sorry I was out feeding the flock. I did mean Dewormed. I use mobile and my phone doesn't like chicken terms...lol
Is she is rattling in the chest then it is a respiratory infection. She needs to be separated from the flock and treated with antibiotics.
She has not been eating if nothing...
Generally green equals no food being digested. Generally it is pure bile when it is green. Does her crop have anything in it? Can you feel anything?
Has she been dewormed recently? Had she been laying eggs and suddenly stop around when you found the green poop?
