Silkies are very friendly, but I'm not sure how they would cope with the heat. Pekins are small, friendly chickens and sussexes lay ,lots of eggs, if you are planning on getting a rooster, they are reasonably quiet. All the breeds I have mentioned go broody very easily (they will sit on eggs). If you want some chickens which lay beautiful eggs, I recommend the Cream Legbar, but I must mention, mine aren't quiet. My first chickens were farmyard-type ones, but after that I got light sussex's and I haven't not had sussex's since!
