Hello and welcome 3spoileddogs,
They really do have personalities, no two hens are alike even if they are the same breed. One of my easter eggers is a sweetie, the other is a flat-out spaz and mean to the other birds to boot. Many people swear by australorps and while mine lay great they aren't fans of any kind of handling. Strangely, in my flock the production reds seek out people and love to be petted while my orpington, which I got because "they are so friendly" is the most aloof. Of the breeds I have, I'd say red sex links, production reds and speckled sussex to be friendliest, while barred rock, wyandotte and australorp less so....your results may vary!
Wishing you the best of luck !
