Hum, I guess it could be cocci but since she isn't lethargic I'm guessing not. Maybe she ate something sharp that cut her insides such as a little glass or plastic. How is she doing right now? Are her poops still bloody?
Hey y'all!
Her poop looks normal. Good advice for the what's the scoop on chicken poop article @Grain Gypsy. But yes keep an eye on her, just looks like she ate some grass and she may just be shedding her old intestinal lining which is perfectly normal.
