Yes, on the advice you received above. I remember my first day bringing home my pekin ducklings - they were very jumpy! Are yours pets? They were bred to be meat birds, so grow super fast, ready to harvest at 8 weeks. Unfortunately that means that many of them need extra niacin to support their leg strength. My pekins were/are pets, and I had one that developed slay leg about the age yours are. She just started walking less and had lots of trouble standing up. What I did was start the liquid vitamin B complex right away. You can't over dose on this. I tried to give it to that specific duck over treats - a piece of bread, peas, meal worms, but I also added it to small drinking water dishes for them, and on top of their feed. If your duck truly has splay leg you can use vet wrap to create hobbles which will hold her legs in proper position. But it may be that her legs are just weak. You can get your ducks to feel comfortable around you by spending lots of time near them, talking quietly to them, and especially bringing them treats. You can introduce meal worms and peas in small quantities to them at this stage - also small bits of zuchinni, watermelon, tiny pieces of herbs or kale. Also, take them out a couple at a time and see if they will settle in on your lap. Ducks don't like change, loud scary things, quick movements, etc. so just take your time and eventually they will get to feel comfortable around you!
