Yes, he gets 100 to 150 of niacin in his water daily. They have all the appropriate stuff like electrolytes, probiotics, chick grit, I give them the right snacks. I switched to Purina flock raiser about a week ago, they go swimming daily. I do everything I'm supposed to, my ducks are spoiled. Jojo is about 6 or 7 weeks old. I feel really stupid saying this, but I don't know what crested means, I'm a first time duck owner. But jojo is my baby, he's sweet n quiet n follows me, loves to be held. I'm worried. This didn't start till he got stuck in his water jug when he was about 3 weeks old, I have no clue how he did it, it was just big enough to stick his head in obviously he couldn't get out. And he was upside down, charlie yelled for me and I got him out and held them for hours. He seemed fine, I'm worried its some psychological problem or ptsd , you know what I mean? What should I do?
