My personal choice/order: Buff Orpington if they have, then Astralorp (sweet like the buff orps!). Then either of the Cochins, since you already have some. then RIR, then the other two - both production breeds. But, I'm not your mother

.
I would really consider either of the first two, as, if I remember correctly, you have
1 buff orpington now, correct? That would give her a similar temperament 'friend' that all in the family will enjoy. My experiences with the RIR are that they can be bullies to others. I know not everyone has had this experience...so it may depend on the line of stock they are from...but I won't get them again. (They are just fine with me, though!)
