Better than throwing rocks at them!
If they came from a big hatchery, they are production reds regardless of what the label on the shipping box says. I have a hatchery New Hamp, good layer, but on the aggressive side. I've heard production rir's can be mean. You will have to watch them when they join the flock. OR... keep them separate, and sell them as pol pullets for $15 each in a few months.
$15 each sure sounds nice.
