OK, I have 13 4-week old ducklings. They are foaging/free ranging during the day with duck crumble available all day and night. I am wondering- what is a normal duck poop supposed to look like? Are there certain kinds of poop that should alarm me? I am seeing a lot of pure liquid poops. They do spend a lot of time in a muddy/wet bog area and love to nuzzle around in it. They get a small amt. of treats like chopped up sugar snap peas, broccoli stems chopped up, crushed whole oats. Is there a good resource of what kinds of poops are normal, and what kinds are a red flag? I'm new to ducks, but I love them so much! I'd hate to be ignorant on the subject. Everyone seems happy and energetic, nonetheless.
