Chicken coops come in many shapes and sizes, but all need a roof, walls, perches, nesting boxes filled with straw, food and water bowls, and a heat lamp for cold winters. Outside of the coop, there's usually a fenced area, or "run," to let the chickens walk around and dust bathe. The run usually has netting on top to keep predators out.  Another possibility is a "chicken tractor," a coop on wheels that you can move around your lawn for free lawn mowing and fertilizer (just make sure there's no chemicals on your grass). Coops can be purchased online, or you can get clever and build your own. Just make sure you can clean the coop and get the eggs out easily.

3. Find Your Flock

There are dozens and dozens of chicken breeds to choose from, but look for a "layer" or "dual-purpose" heritage breed for the best eggs and hardiest chickens. You're probably going to want female chicks, since roosters don't lay eggs and are sometimes not even allowed in urban areas. Mail-ordered chicks are usually not sold in small numbers, so unless you're starting with a flock of 20 hens, then you might want to check out your local feed store. A feed store is an all-purpose shop for farmers, and if they don't sell chicks, they'll probably know someone who does. Chicks need special care. You can also buy "pullets," or teenager hens. They usually start laying eggs at 4-6 months old.

4. Feed 'em

You can usually buy "layer" feed for hens at the feed store (chicks and pullets require their own kinds of feed), or make your own out of different grains, seeds, and legumes. Many recipes for homemade chicken feed are available online. However, all chickens need calcium (usually from ground oyster shells), grit (sand or dirt, which is not a problem for free-range hens), and lots of water. "Scratch" is a chicken treat combined with entertainment: whole grains scattered on the ground for the hens to search for before eating. Chickens are also great recyclers, and will happily nibble lawn clippings, weeds, and vegetable trimmings. They'll even forage in your garden for insects and leaves, if you let them. Chicken manure makes fantastic compost, in case you were wondering. 

5. Enjoy Your Eggs!

Once they're old enough, hens will start to lay. If they don't lay in their boxes, put a golf ball there to tell them it's a good spot for eggs. A flock of 3-4 chickens will produce 1-2 dozen fresh eggs per week (more eggs in the spring and summer than in the winter), which is more than enough for most families. Homegrown eggs will have dirt on them, so wash them off with warm water right before eating, like you would whole fruit.
