I havent had a problem with the Leghorns..Actually, I love hatching their eggs and raising them, and they are my favorite of the flock...It isn't so much as how much you handle them, as it is the breeding.
My first leghorn rooster was a jerk...Attacked us everytime he saw us (note- we ate him for supper)...The one I have now is awesome.
They can be flighty, but they will warm up to you - especially if you handle them a lot. They most likely wont be lap chickens, but they will follow you around. Just give lots of treats, and they will love you forever. I barely handled last years stock and they are very friendly. We fed them lots of vegetables, fruits ect this fall, and made sure they saw it came from us. Now the follow/chase us around the farm, and when we go in the coop to collect eggs, they run over and look up and beg...
I wasn't too fond of the stars, just because they seemed dumber (if that's possible) than the other chickens. They were incredibly friendly though!
Both breeds are good layers...Though the WLH's were by far the best producers!
This seems like a subject that you are going to get tons of opinions from! Its great to hear other peoples experiences with the different breeds though
