Is there anything else that can cause blood in poop. I know its not the shedding of the intestinal wall I've seen that. I had one with what appeared to be cocci and I had run out of kocci free which is what I use with fantastic results. So I made a mash with her food and added some things I know to help with parasites from my herbal training. I used about 2 cups feed with enough water to make a mash and about 1/2 tbls of turmeric, some ginger, some fresh diced garlic, some cayenne pepper, and a touch of unpasteurized local honey. Within 12 hrs her color wad back and no more bloody poop. I fed this to all 5 chickens for 5 days and the one that looked sucks is back to her normal self. I read an article on turmeric a cocci a while back so my gut told me to try it since I don't really have much available locally. I have to order all my meds online even natural which I prefer. I am pretty sure it was cocci since the conditions where right and out of my control. It just kept raining.
