Feeding Silkie chicks with duck and goose crumb

[DrChickenKev]

Hey again all

Looking for some friendly advice

I have a muscovy sitting on 12 silkie eggs and they are due to hatch next weekend (around 12th July), I had already bought some duck and goose crumb I also had another muscovy sat on her own eggs, but they were all infertile

So I have 20kg of duck crumb and no ducklings

I know ducklings shouldn't be fed chick feed due to the medication, but is it ok the other way around, can I safely feed duck and goose crumb to baby chickens?

Thanks in advance - pictures when the lil balls of fluff arrive...
