It sounds like gut lining, I did a load of pics of poo, havn't managed to capture a gut lining one yet. If htis is what it is its nothing to worry about.
If its cocci the poop will be all fresh blood, very much like a vein been cut. You will have to stay out wit the bird and follow her around, if its cocci, every poop will be the same.
The poop pics are here
If it is cocci, she will need treating with Coxoid which is available through alot of outlets or a vet script.
