guineas behavior

My guineas are approx 2-3 months old. I've had them since keets. They have been in their coop/run outside for about a 1-2 weeks. But tonight they didn't come home bCk to thier coop, Im worried. Will they come back tomorrow?

Okay so our biggest issue is goshawks - ferocious, aggressive, and brass goshawks hunt our free range chickens. They will try to murder them right on our porch! We do our very best to deter them. We recently added some guineas (successfully; knock on wood) to our flock. Still not 100 on both...
