Can 7 week old ducklings eat too much grass?

[CoriM]

My ducklings have been spending a good portion of their day in the grass this past week and I notice that when I bring them in their poop is so filled with grass - and it's like that through morning. They don't seem to eat much of their feed overnight anymore. Can they eat too much grass? They are fully feathered and almost ready to move out permanently.

They will know when their full having grass in manure is normal when there eating it and if they feel like their hungry, they'll eat their food.

They can't really eat to much grass. If you are seeing grass in their poop they are not getting enough grit.

I have grit for them - it just seems really green like digested grass.
