Just watch out on Backyard Chickens... a lot of their stuff tends to be a bit... overboard?! Chickens don't need coats, air conditioners, or ridiculous levels of pampering. Sure, if you have the time, money and need for a pet, you can indulge yourself, but they do just fine with clean water, a good layer mash on demand, and plenty of space to be chickens.
They do need adequate protection from predators... for most people, neighborhood dogs and cats are the biggest danger. And selecting a breed which is appropriate for your climate (a smaller, light colored type if you live where it's hot, heavier types with rose combs if frostbite could be a problem) will prevent a lot of problems.
Above all, enjoy them! They can be endlessly amusing, and fresh eggs are wonderful!
