The female duckling originally posted about is still quite weak. She's been under treatment for five days now. She can stand and walk, but certainly is weak. When she does stand you can see increased effort. She's definitely eating and drinking (she's marginally larger than the other ducklings, probably due to lack of exercise). She lays around a lot of the time. Yesterday and today we started outside swimming and she swims as well as the other ducks. I've been trying to get her to swim an hour a day. Then we slowly walk around the yard as a flock (abusing that imprinting, while I still can) and she does keep up with the other ducks. If I stop, she lays down immedially.
The only time she seems normal is in the water. Does anyone have feedback on if we are on the right track considering we are 5 days into treating this potential niacin deficiency or should I consider another issue? I can post pictures if needed. I checked for bumblefoot but that appeared normal. She doesn't appear to have a splayed leg. I'm not sure what her issue is.
