A few tips on chicken care from my own experience:
Chickens will live in an old dog house and dog pen. There is no need for a big investment of hundreds of dollars for a coop and supplies. As long as they have a protected dark area for nesting and roosting, they'll be fine. You may need to add a small perch to the dog house for roosting; the perch can be fancy or just a log.
Chickens don't need a rooster to lay eggs; just think of the hundreds of thousands packed into little wire cages in the egg factories.
Laying eggs is a light-sensitive operation; if you don't add artificial light to the coop in the winter when the days are short, they will stop laying for about two months. If you add a light to lengthen their day, add it in the morning. This keeps the chickens from injuring themselves in the dark if the light suddenly goes out in the evening.
Eggs will last up to three weeks at room temperature. With a small backyard flock of five or six birds, there's no rush to raid the nest several times a day (like some books state). But leaving the eggs too long in the nest can create egg-eater chickens; this is a habit that is hard to break, if you can break it at all.
Train your chickens to come to a call for treats; this helps immensely when trying to round them up into the pen. You've heard of the expression "herding cats"; well, it's the same for chickens. They go into the pen normally in the evening, but not any other time of day, when you need to put them away (like when they're digging up seedlings in your garden).
I use cheap bird seeds as a treat, along with a consistent call: "Chick-chick-chick." By the third or fourth time, they come running to that call.
I recommend further online reading, like this awesome forum/message board on chicken care calledBackyard Chickens Message Board. Other good reading on coops and care can be found at The City Chicken, BackyardChickens.com, andFeatherSite - The Poultry Page.
Enjoy your chickies!
