Thanks for your detailed reply.
I don't live in the US and duck feed is really difficult to find here, I even tried ordering it online but didn't find any satisfying results.
How do I know if they have problems with weakness in their legs?
They do sleep a lot tho is that a bad sign?
They are about 3 weeks old and they've been outside like 2 times so far.
They mostly eat rolled oats and vegetables.
I recently started feeding them bulgur and bird seed
