I truly think if you handle the chicks a lot while growing up they all can be friendly. I hear all the time your leg horn is so friendly I’ve never seen one cry to be pet or handled.You should have at least 4 s.f. in coop and 10 s.f. in run per bird. And while we're at it, ventilation = to 10% of floor space, or 1 s.f./bird, perch = to 1 l.f./bird. I've had all of these breeds in my flock. LOVE Doms and EE. SLW are pure eye candy, but don't have the charm of the former two. Check Henderson's Chicken Breed's chart for more info about breed selection.
Or some Buck Eyes! or... or... or... Just like a kid in a candy store. Al makes a wonderful
suggestion. a bit of white would really make the other colors "pop". Leghorns also come in a rose comb, and in a variety of colors.
