Y’all have been amazingly helpful and I’m learning so much! But I’m back with a couple more questions. (I’ll surely be back regularly as we enter new stages) Our muscovy ducklings, Feather and Pip are 4 weeks old now. They have lived on non-medicated crumbles that I added niacin supplement to since day 1. We offered treats for the first time last week, mashed blueberries, frozen peas ( mostly thawed but not cooked to start. They didn’t seem to love it lol. We learned here about other fruits to try and also just read that they love grass, dandelion weeds and certain leafy greens, and they can have as much as they want. I didn’t find at what age to add these to their diet. We have never offered any before, but I read many different opinions about how to administer as well as what age to start adding “grit”, but commonly see recommendations to add it around 4 weeks old, when they start weaning off the starter feed. They have about 1 more day of the starter crumbles so we will buy the next growth step feed tomorrow. My questions are, what is “grit”, and how do I add it to their meals? (Sprinkled over the food or in the drinking water)? And how much should I give per feeding? I know I could ask at the store, and I’ll ask a store associate to guide me which feed and grit is best at this stage, but it’s much easier for me to understand when I can return to your advice and answers here as needed. I plan on offering finely chopped kale and romaine lettuce to start. I want them to be able to digest it safely so I know they need grit served with it. I just don’t know which opinion is correct, over the food or water? Or does it make any difference? Thanks y’all.
