Pekins - fab, friendly, cheery-faced, happy little souls! Lovely little eggs.
Wyandotte bantam - friendly, lovely eggs, calm.
Welsummer - beautiful, but easily spooked, very flighty, still legs it when I go in the run after months of being nice to her...and sometimes horrid to the other hens, despite not being in charge? no eggs yet, so don't know about that.
Cochin - huge, ball of fluff, very placid and friendly (slow to mature, and no eggs yet)
Cream Legbar - not very friendly, but surprisingly calm, after a bumpy start as a complete drama queen who couldn't find her way into coop at night, and had to be lifted in screeching that we were trying to kill her! No eggs yet.
Rhode Island Red - calm, reasonably friendly, bustles about, lays nice sized eggs, and laid a whopper today of 79g!
Copper Black Marans - not very friendly (but have only just got them at 19-20 weeks ish), getting better, they walk speedily to the other side of the run now, rather than the mad, panicked flying away they did at first... (the meal worms are helping!), think we've had one egg, but it wasn't very brown, so might have been the Welsummers (it was spotty)
I would recommend all of them except the Welsummer, but she might be an odd one, as others have said they are friendly
