I know you are now off to coop discussions but wanted to add my 2 cents about friendly breeds. Our daughter started this as a 4-H project for husbandry and eggs. We have had Australorps, EEs, BRs, BOs, mixed breed bantams, a Delaware, Wyandottes (GLW & SLW). For a friendly breed, my experience has been that you just can't beat the Barred Rocks. One of ours was raised my us from a chick, the other we got from a breeder and the bird wasn't really handled. Both of these girls are like lap dogs! Very sweet. Their eggs are usually just mediums and they don't lay everyday but they are very tolerant of just about everything. As for egg laying - nothing out lays our Wyandottes. They aren't as friendly as the BRs but they are egg laying machines! They aren't flighty but they don't relish being picked up - then again, they weren't hand raised as chicks.
Good luck with your chicken adventure! We really enjoy our birds and I can't imagine not having them now! The eggs are a plus at this point b/c the birds are just a joy to be around! Our daughter Sophie sits on a milk crate in their run and sings to them, etc. Excellent!
