Could this be the problem? I’ve read protein should be 19-21%?
Oh no, that's a layer feed. Way too much calcium for ducklings. She needs to stop feeding that ASAP. Too much calcium can cause kidney damage, bone issues, kidney failure, seizures, etc. And death.
And yes, also not enough protein.
She needs to switch to a chick feed immediately. Or it looks like that brand has a duckling feed if she wants to stay with that brand, which would be even better.
