Hi guys, I'm new here. I recently got 3 Pekin and 3 Khaki Campbell babies. I've estimated they're around 3-4 weeks old. One Pekin has lame legs. He can walk/stand but doesn't prefer to, and often just lays down by himself. When he does walk, he "paddles" his feet out sideways like a weird cartoon. I'm guessing this is a niacin deficiency. I have started them on Brewers Yeast (in the water, and I let them nibble a little bit from my hand.) A few questions, however: - How long should it take before I see and improvement in my limpy duck? Could these feet be a different problem other than niacin? - Is it normal for one duck to develop a niacin deficiency, but not others? I love my little Forrest Gump duck more than the rest because he needs it the most right now and I want to nurse him back to health good and strong! I get so worried and get up to check on him 3-4 times throughout the night to make sure no one is sitting on him and he can't escape, haha. Thanks for the help guys!
