Hatching
my pekin duck since yesterday hasn't been able to walk and sits where it falls down. his legs are really warm and i'm not sure if he has a niacin deficiency. i feed it brewer's yeast with all of his food (veggies/leaves, lettuce, greens) is it a growth spurt? this happened before several weeks ago when he couldn't walk but the next day he was just fine. he's about 2 1/2 months old and he's getting really big. his starting to lose his yellow fluff.
