My flock of buff orpingtons have green poop

[Alg687]

Just this morning my flocks poop is normal but green colored. Is this something to be concerned about.

Such a pretty green, kind of the color of grass. If you have lots of green grass and the chickens are allowed on it, they've all been eating it.

What they eat can tint their poop. Carrots make the poop bright orange. Purple cabbage makes magenta poop. This last one is my favorite.
