Pros: Egg laying
Cons: Agressive in the flock
My dad has RIR's and we kept his with ours during their chick stage. They were always dominant in our flock and would be fine with humans, but definately on the top of the flock. They are thankfully now with him and are always puffing up their personality with one another. Dad recently added some bantams and the RIR's are big bullies cornering the bantams, ganging up one them and will not let them to the water. I will not have them in my flock.
