Any breed that you raise from chicks will be friendly with your girls. As for year round laying, the only way to assure that is to add supplemental lighting to your coop. Not everyone thinks that is healthy for the hens, but if high production is your goal, that is the only way. Sure, some breeds have a reputation for laying well in the winter, but I doubt anyone has done any actual tests that are meaningful, it is all anecdotal and often passed down as statements of fact. I do add lighting, but start in December to give everyone a rest. I am trying to rush spring, not make them think it is always summer like the commercial facilities.
Personally, I love Cream Legbars for almost every situation. I didn't want to like them, I thought they had to be "over hyped" by the people trying to get rich quick selling them, but my own experience and that of every customer that has reported back to me, is that they are wonderful backyard birds. I wouldn't recommend them for unsupervised free ranging, they are too placid to avoid predators. And some of the roos get feisty (compared to my other breeds), but the pullets are great, doubly so when hand raised by children.
