Dark poop

[shellbell]

One of my baby chicks (2 weeks old) has had dark, (black) kind of runny poop. It acts fine, eating, drinking, active. Any idea what is causing this? (it had the dark runny poop the day I brought it home)

1) Are you certain that only one chick is producing this dark poo?
2) Are there any other (more "normal") poos being produced in-between the dark, runny poos?
3) Is it pudding runny or total liquid?

Personally, I go more by activity level of the bird as to whether there's a problem or not - rather than what the poo looks like (unless blood is in the poo). There's just such a wide range of normal when it comes to chick(en) poo...
