Hey all ducks are acting fine but I have notice some lime green poop....what does that mean....they eat mixed flock crumble nothing new to diet....I have about 65 ducks and there all acting fine minus someone's poop color

Could it have gotten any vegetation to eat? Have you seen any sitting instead of coming to eat crumbles?

No there in a building for winter so no greens and none that I have noticed have been sitting around I know it's a smaller duck with the green poop

Although they have many food bowls and they have food 24/7
