I bought a RIR pullet in March of 2012, though at the time she and the other chicks in her bin were being sold as Welsummers. Had I known she was a RIR, I probably wouldn't have gotten her. It's funny how things work out, because she's now one of my favorite chickens out of the 12 or so different pullets I have.
I had never really wanted to get the RIR breed because I had read that they were aggressive birds, and I didn't want any born fighters in my flock, if I could help it. The pullet I have does have some competitiveness to her, but I've never really seen her start a fight with any of the others. She's clearly the head of the flock, and she's one of the boldest birds I have, as she's often one of the first to check out new things or new people. She has always been friendly with me and my family, though I've noticed a few times that she feels the need to nip at my pant leg or hand when she thinks I'm not getting her food fast enough. This behavior is pretty short-lived, since I get after her by either picking her up and carrying her, or poking her in the head to "peck" her back. So far as her being a "mean" chicken, though, I have seen my sweet little Wyandottes pick at the other birds far more than she has done.
I listed noise as a con for this breed because I've noticed that she is the loudest chicken I have. Her noise actually doesn't bother me, as I like chatty hens, but if you're in a small yard with easily irritated neighbors, beware.
The pros of this breed definitely lie among the outgoing personality (with reasonable handling) and a good egg laying ability. Of the three birds I currently have laying, my RIR is the most reliable, laying better than either my Buff Orpington or my Black Sex-link, though all three are still new to laying.
Over all, if you're looking for a good egg layer, I would consider this breed. Be mindful of their aggressive streak, especially if you don't handle them on a daily basis, but also be aware that they are not bloodthirsty chickens.
