Have you wormed your flock lately?
No, I haven't wormed yet and haven't seen anything to make me think of worms, I've checked all her poo and nothing.
Have you checked them over for lice, mites, or signs of their eggs clumped at the base of feathers?
No lice or mites.
Check her crop. It should be full in the evening and empty in the morning... If it's hard or spongy, she could have sour or impacted crop.
Her crop is empty.
Coccidiosis is also a possibility, and not all strains cause the bloody poops.
I mixed up a dose of Corid just for her.
Any runny nose, bubbly eyes, sneezing, wheezing, or anything like that?
Her nose isn't runny, her eyes look find, no sneezing or wheezing. She only had some water come out of her mouth when I had her almost upside down checking for parasites. It hasn't happen since. She just stands and today not as much water as yesterday.
