There are soooo many things that can go wrong in a chicken's body. Their reproductive systems are so prone to problems. Their lungs can be so fragile. They are susceptible to so many illnesses. I've seen similar poop pics on BYC from cancer, serious injuries, infections.... My own girl had black poop before passing from salpingitis.
And if you send her for necropsy, you won't be able to bury her, but you might be able to prevent other chickens from getting whatever she had. Getting a necropsy for my girl Magnolia helped in that I realized there was nothing more I could have done for her and that my other chickens weren't going to catch some awful infectious disease. Also, talking with the technicians, they gave me info on how she might have gotten the infection and how I might be able to prevent it in others. Without that, I would have been left guessing. But I was very sad that I never got to bury her. I still am.
I'm not telling you what I think you should do, but I thought sharing my experience will help you make an informed decision.
I am very, very sorry for the losses you've shared with us. You are clearly a strong person. Virtual hugs...
