We just took in this duckling (about 4 weeks), and I knew they weren't giving it the extra niacin it needed. We bought a supplement, and at least I see it standing more (it laid around a lot). It doesn't seem to have any problems swimming. It steps on its own feet when it tries walking. Is this something it might grow out of, or am I going to need to try and correct it with some taped up contraption? Thanks!
