We have 4 eight week Old Pekin ducks! We absolutely love and adore them, except one of them is having some difficulty walking. He is severely pigeon toed! He tries so hard to keep up with the other three but constantly steps on his own feet and falls, then just kind of lays there. It breaks my heart! I always have to pick him up and carry him to wear the rest of the flock is. I've read some things on a niacin deficiency causing the problem, Luck of the draw, or a splint of some sort to help correct it? Anyone have any ideas? Is he too far gone at eight weeks to correct it?!
