Can chickens get green poo from eating too much lettuce and grass hay? We recently gave the flock a bag of mixed greens. Then I changed their coop bedding and put in some older (not moldy) grass hay that my llamas wouldn't eat (they don't like to eat it when it gets too bleached out). Since the lettuce and hay I've noticed green poo. Could it be from all of the greens or do they have something else?
