Definately check out the poultry thread - HERE
Caring for the chooks is quiet easy, it's setting up (nesting boxes etc etc) & dog / fox proofing that were the biggest things for us.
Our girls get our food scraps (no meat, no citrus and a few other things discussed in poultry threads - you might have to go through a few) and a seed mix, we have a water & feed hanger and we let them 'free range' almost every day for most of the day.
Our girls love them and have never been pecked, the chickens greet us at the gate & follow the girls into the shed, we pick them up and handle them and don't have any issues.
