What does this poop mean?

[Ccort]

All three came from same chicken, within short period of time.

How old is this bird? Any symptoms like are they eating and drinking normally or lethargic? Is this a hen? If so, is she laying?

The dark poop, does it look like blood or is it black? If you can't tell, you can smear a little on white paper.

It could be a sign of worms. If you haven't wormed them recently, you could try that. Safeguard (fenbendazole) liquid Goat Dewormer is a popular dewormer for chickens, administered orally at 1/4 ml per pound, with repeat dosing after 10 days. Valbazen (albendazole) is another one.
