Something attacked all my of my hens and killed them except one. Mary Ann who is a Brahma is still breathing (checked her heart rate and lungs) (I’m a vet tech) she has a wound but is also in shock. I gave her some sugar water and she is wrapped in a heated blanket she seems to be more responsive by the hours but I’m not sure if I’m doing the right thing what else can I do for her. How long could this last. I am aware that she could die in the morning .
