My Magpie ducks are two weeks old today and no sign of feathers. My sisters ducks (Pekin) have pin feathers at the same age .. My brooder to warm? The are double the size and weight but no feathers. I raised rouen and Pekin last year and my pictures show some feather development on trails and wings at two weeks . Magpies slower to feather out? Have them on non medicated chick starter and brewers yeast.
