My wife finally relented and it appears we will be getting some chickens for our backyard. I plan to keep about 6 or so in our slightly above average Houston-area yard (0.3 acre lot). As far as breeds go, a local guy has barred rocks, Rhode Island reds and black sex links. Of the 3, which are my best option? I don't mind mixing and matching and might actually prefer that. Number 1 priority will be docile, as we have 1 year old twins. Then productivity, then looks etc. I plan to free-range them only putting them up in the coop at night. Any other advice beyond breed recommendations for a newbie?
