What hen can I add to my coop?

[Italian-gal]

I have 1 hen, she is a about 6 months old an is a Barred Rock. I would like to add another hen about her age and want to know what other types of chicken my Louise will get along with. Would like one that can hold her own and lay eggs.

since barred rocks are a friendly docile breed any other hens you add should also be docile, other more aggressive breeds can bully barred rocks.
orpingtons are a good docile breed, as are wyandottes, both are cold-hardy and are good layers
