It’s the only vitamins I found for ducks, liquid something and I have to mix it with water, the vet told me to buy this. Also I feed them starter food and a lot of veggies and fruits. And they’re out all day in the garden so they eat anything. The smaller one with the leg problem could’t walk for days but ate a lot and for now it’s perfectly okay, it can jump and stuff but the leg is bent and down from the knee doesn’t moves. But the duck do use it for scratching. Here are two pics where you can see it, but I can take more photos tomorrow. (The brown one) The one in the water is older but the other one i took today
