Why Is There Blood in My Chicken's Poop?
Blood in droppings in young birds is coccidiosis until proven otherwise — start treatment the same day; in adults, sort true blood from shed intestinal lining.
Most likely causes
Coccidiosis
What points to it: Chicks/growers 3-20 weeks especially: bloody or dark tarry droppings plus hunched, ruffled, cold-acting birds huddling under the lamp, going downhill in a day or two.
What to do: Amprolium (Corid) in the water for the whole group immediately — it's cheap, gentle, and the delay is what kills. Dry out litter (cocci breeds in damp bedding), and don't wait for a lab to start treatment when the picture fits.
Shed intestinal lining
What points to it: Occasional orange-red stringy or tissue-like bits in an adult's otherwise normal dropping, bird completely fine.
What to do: Startling but normal — intestinal cells slough and pass. No action if the bird is bright and it's occasional.
Vent injury
What points to it: Fresh red blood streaked ON the outside of a normal dropping, or around the vent — from a pecked vent, a rough lay, or early prolapse.
What to do: Examine the vent directly; cover wounds, isolate if pecked, and see the prolapse guide if tissue is involved.
Worm burden or enteritis
What points to it: Chronic dark or bloody-tinged droppings with weight loss in adults.
What to do: Vet fecal test — targeted answer beats shotgun treatment in adults.
Check these first
Age of the bird, freshness and pattern of the blood (mixed in vs. streaked on vs. stringy tissue), litter dampness, and the bird's attitude. Take a photo of the dropping — Harold or a vet can do a lot with a clear photo.
When it's probably nothing
The occasional shed-lining bit in adults, and reddish cecal droppings after certain treats (beets famously terrify keepers), are false alarms.
This guide is experienced-keeper guidance, not veterinary care. When a bird is crashing or a symptom is spreading, a poultry vet or your state extension lab is the right call — fast.
