Feeding black sunflower seeds...hows and whats

[WIChookchick]

On the subforum for injuries, they often say to boost their protien by feeding black sunflower seeds...
My questions are...
IF the flock has never had it before, how do you introduce it?
Do you feed the seed or the hearts?

ANy info is good.
Thanks

Use the black oil sunflower seeds and just throw it in or hand feed them,once they relize what it is they will devour it.I mix mine in with my scratch in the winter.
