My top hen is Brigid, a buff brahma.
I have a small hen that is so dainty in her habits that I named her after a dear elderly friend of mine, Maggie.
She's sweet and loving with me. She's a tyrant with the other hens.
Of course my rooster Thor is king of the whole domain, but even he backs down to Brigid.
My RIR are on top of the pecking order and the Easter Eggers are at the bottom. The leghorn answer to no one and hang around by themselves. The BSL are kind of mean and as they get older may take over at the top. The BR pick on the EE.
