We also live in an area with a lot of hawks, and as a result, I have rehomed most of my white chickens (easy for them to be spotted from the air).
I highly recommend white faced black Spanish. They're flighty, gorgeous, and can fend for themselves pretty well. I have 16 of them (4 males, 12 females) and absolutely LOVE them. We have Easter eggers, a couple of blue/wheaton ameraucanas, a partridge rock, a black austrolorp, a silver laced wyandotte, and a few other breeds, but the WFBS are my favorites. They will also be good layers.... as a general rule of thumb, white faced black Spanish chickens will give you 4-5 large, chalk-white eggs a week per hen, up to 6 eggs a week during peak laying months.
They also free range well. But they're just so darn PRETTY.
