Hi, new to owning ducklings, just over 3 weeks old. I done a lot of research before getting them, chick crumb with brewers yeast on top, peas for treats with grit to help them digest. Recently one of my four have become unsteady, wide stance and sit down a lot. I’ve bought some vitamin b complex to put over treats but unsure if I’m missing anything! Please help 
Glad you joined.
Some ducklings just need extra we see it a lot especially Pekin and other large breeds but Pekins mainly they grow so fast. Here is info on Niacin deficiency and it will show you what the dose is for your ducklings.
