So I have 5 ducklings, 2 mallards, 2 Pekins and a cayuga, they are approx 3 weeks old, and one of my Pekins seems very pigeon toed, ie stepping on his own feet, hips seem to jut outwards.. He gets around just fine, eating drinking normal, and just as active as the other ducks, wondering if maybe niacin deficiency or maybe just a genetic problem from flightless birds... I will post pics as soon as I learn how
