Will the other chickens kill the newly hatched chicks?

[briter30]

I have got a broody hen that I am going to let sit on some fertilized eggs. If my eggs hatch, will the other hens kill the newly hatched chicks? Do you have to separate the hen before her eggs hatch? Thanks for any input.

if the chicks were hatched under or "adopted" by a hen she will protect them till they are old enough to fend for themselves.
