I recently acquired 4 Pekin ducklings from someone who mail-ordered them but then couldn't keep them. I was told they are 2 weeks old. One of them is very bow-legged & I need to know what to do for him. He has a very wide stance, as if he just got off a horse he'd been riding all afternoon. His legs from hip to hock are at a 45 degree angle to his body, then his lower legs from hock to foot are at a 90 degree angle to the ground. So far he doesn't seem to lag behind the others when walking around. I began giving them all some Poly-vi-sol vitamin drops as soon as I got them home, a few drops in the AM & the PM. They're eating Purina Flock Raiser. No photos are available to post, sorry. Is this a good course of care? Is there anything else I could give, to the bow-legged duckling & also to the others? Thank you for your imput.
