Help!! Possible Cocci and Swelled Crop/Sour Crop? Pics attached

[asher42069]

On Saturday I noticed one of my silkies had a swollen crop, not hard, balloon like. She has had ACV in her water since, I’ve given her some warm water mixed with veg oil, massaging her crop whenever I get a chance from neck to breast, and started monistat on Monday 2x a day. Monday I noticed two of my bird were pooping blood, went and purchased Corid and mixed 2 tsp per gallon and it remains their only water source, mixed fresh daily. Today I noticed my tiniest chick has a swollen crop and is lethargic, not eating or drinking, and has been huddled under my silkie since I pulled her out to isolate her this morning. When I massage her crop she has some clear non-odor liquid gurgling into her beak. My silkies crop is also still swelled but she is acting normal. Please someone help! What else can I do? I attached some photos of the poo and baby chick.

When that much blood is present, it's likely that necrotic enteritis has developed from inflammation of the intestines. The chickens will require a sulfa antibiotic https://jedds.com/products/trimethoprin-sulfa-medpet?_pos=1&_sid=83dcb7a2a&_ss=r in addition to the Corid. For the sickest ones, add a drench dose of about .2ml or .3ml undiluted Corid directly into the beak. Give it like this.
