First of all, thank you for asking! I appreciate your concern!
I have named him/her Lucy, and until I find out otherwise, I'm going to assume he/she is a girl.
She is doing okay. I actually have her on my lap right now.

She is is still wobbly. When I go into town later today, I plan on getting some Brewer's yeast from wal-mart. I hope it helps.
I had her on my lap for about half an hour today, and I didn't notice any drainage from her nose.
I took her and the duckling outside yesterday, and they stuck pretty closely to me. They seemed to enjoy themselves, though. It's kinda windy to take them out today.
She still seems to have runny poo that runs down her underside to her belly. However, it's not sticking to just her vent any more, which is definitely a good thing, and she doesn't have as much stuck to her as she used to.
Overall, I guess I'd say that she's doing well, but still has some improvements to make. The duckling (whom I've named Lucky) is larger and older than Lucy and doesn't seem to mind knocking her over or pushing her out of the way. I've wondered if I should separate them 'till Lucy becomes steadier, but I only have one heat lamp, so I don't think I could make it work.
