for someone starting out, I would recommend looking at Craig's list and getting point-of-lay pullets. (pol) -- Search your local Craig's List for "pullets", or hens. Be very careful that you don't get chickens with diseases....some unscrupulous people have used Craigs List as a dumping grounds. Kind of interview the sellers. If their reason for selling seems reasonable. Depending on where you live, you could also check the livestock section of your local paper.
ETA - I just checked the local Craigs List here---and I have to say there are some excellent chickens for sale. Some are from folks here on BYC. (I may have to go buy some)--- The prices are higher than I wrote before - feed costs have gone up -- but still worth the price.
A good breed to look for is Golden Comet sometimes these birds are called red sexlinks, or golden sexlinks and there are also black sexlinks, they can go for about 8.00 per hen or even less depending on the going rate in your area. They are healthy, friendly birds that produce close to an egg per day. They also eat less and produce more than most birds.
Depending on the reason that you want chickens -- you will have less time to wait, fewer risks of the babies deaths as they go through the chicken growth....and you can know if you want chickens for the long haul. Barred Plymouth Rocks are another good backyard breed. Many people are buying more chicks than they want long term, with the thought that chicks will die - one person gave the advice 'get twice as many as you want to end up with'.
When you say buy-or-build, I'm thinking you mean coop. -- presently
TSC (
tractor supply) has a combination coop and run - with 2-nesting boxes, that have external access and an attached little run, all under a roof. It is wooden and bolts together - price is around 199.00 -- If you buy it--you could bolt it together in a very short time and be ready for chickens in an afternoon. Keep the box and if you decide at some future time chickens are not for you--you could scrub it up --dry it off -- put it back in the box and sell. (you will probably discover chickens
are for you --and then you can use your little coop for an isolation pen for when you get new chickens, or if one needs extra attention, separation , etc. There is always a use for a little coop when you have chickens) ETA - Of course after you have built your very big coop if you get carried away by chicken math and decide you need one-of-each.
This little coop is also one that has a slide out poop tray. There is a thread here by Trish that is so brilliant. With a bag of pdz (a horse stall additive) and a couple of kitty littler scoops, you can have a sparkling clean coop in just moments a day (like scooping kitty litter) put the scooped droppings in a pail and in time have valuable compost for you garden or flower beds..... Couldn't be easier as far as keeping clean -

The thread is huge---and lots of people have hopped on - but Trish makes the points very clearly in the first couple of posts with answers to questions...it is as easy as cleaning the kitty litter box.
For about 450.00 you can get a snap lock coop. Would hold a few more chickens, but being plastic it wouldn't require painting ever, and could be hosed down...same approach...you could snap it together in minutes....resell easily if you decided you don't want chickens at some future time, so your investment could be partially recovered. Has slide out poop tray. Plastic coops are also less friendly to redmite populations so the extra investment may be well worth it in the long haul. SnapLock Doesn't have the little enclosed run area though.

Hopefully you can/will be able to free range your chickens in your yard, but -- when you are gone they should be penned for their protection.
If eggs are your goal, pol pullets cut the waiting time from months to weeks, and you can be more certain that you really won't get roosters. Backyard chickens can be extremely rewarding. Some folks in England have amazing discipline and keep a few hens at the bottom of the garden. Seems folks in the states have a bit less restraint - LOL.
You can start small with little risk -- see how it goes -- and as time passes you can add to your flock and get in as deeply as you want. -- In the meantime -- you can have those nice little clucking creatures in your yard, get eggs, put out not too much serious cash while you decide if it is right for you.
Depending upon where you live - varmits - raccoons, coyotes etc, or neighborhood dogs can be a threat to your chickens....and heat is a serious threat if temperatures get above 102...so make sure that you have shade for them in summer.......
Meanwhile - once you get your first eggs--you will wonder how you ever got along without your own chickens. It's nice to get a hen and two pullets, and get your first egg the very next day. I'm surprised more people don't do this....and if you add the cost of lamp, feed, brooder and your time -- it is far more cost effective to get a hen than a chick -- at the prices people sell hens for.
