HELP PLEASE

[CLAMAR23]

I bought two baby Pekin ducklings from a local store, one of my babies “knees” look swollen and odd, he doesn’t stand for long periods of time and often falls over trying to walk, I thought it may be a niacin deficiency but the vitamin B3 complex and peas don’t seem to be doing anything..

Can you post some pictures? How old and how long since you started the b3 is it just niacin or actually b complex?
