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 .
Hens go broody when you don’t want them to… and won’t go broody when you do.
So far you're doing the right thing. Have you tried treating the wound yet? Feel free to post pictures so you can get better guidance on what to do next.
