Here are my ducklings @ 3 weeks old! I'm truly amazed at how fast they grow. Yesterday they only had pin feathers (growing adult feathers are called this right?) on their wings and now they have some on their necks/backs. They are quickly outgrowing their brooder so I'm trying to find another place for them until they can go outside.
I'm also having so much trouble finding niacin. I'm just going to make the trek to an organic store tonight (45 mins away) to get Brewers Yeast. None of our grocery chains sell that either.
We still haven't officially named them but my daughter calls them "Purple beak" and "Orange beak" She loves those ducks!
For niacin and/or brewers yeast try eBay or Amazon. I found both really hard to find even in organic or health stores. Brewers yest you might also find at a wine store if your lucky. Found mine there. Maybe try calling the store instead of driving there? Saves you a long and disappointing trip too.
