I'm new to this site and ducks! We have 5 white pekins and I'm head over heels already. We bought 2 on one weekend from TSC and then went back the next week for 3 more. They all seem to be doing well, except one of my older 2 lays around all the time. At first we just thought it was a really relaxed duck and called it Shalom since it was so peaceful. The other we called Wiggles because it goes crazy when we pick it up. Shalom just lays happily in our arms. I've added brewer's yeast to their food to help, but it just lays around and when it tries to walk it's like it's too weak to do so. Sometimes I see it walking around a bit, and when I get it into the bathtub for a swim, it's very lively. I just didn't know if there was something else I could or should be doing to help it.
