I have 45 Khaki Campbell ducklings that are one month old. I recently found one that has difficulty or can't walk. I bought some niacin yesterday because I read here that this type of thing could be a niacin deficiency. I also brought her in this morning for a bath with a buddy. I noticed that her feet are not spread out like her buddy's. She doesn't have yoga toes. She's not really swimming in the tub either. She just floats. In the first photo you can see her buddy's foot. Looks like normal duckling. In the second, you see my special needs case. Is there any hope for her?
