Cultures: The Farms of the Lab

Step into a microbiology lab, and you might feel like you’ve wandered onto a tiny, futuristic farm. But instead of cows and cornfields, you’ll find stacks of clear dishes filled with jelly-like soil and colonies of colorful “crops.” Welcome to the world of microbial cultures, where scientists become the world’s smallest-scale farmers, cultivating invisible life into lush, visible harvests. Just as a farmer tends the land to grow food, a microbiologist cultivates bacteria, fungi, and other microbes on nutrient-rich media. These miniature farms don’t just look cool—they are the heartbeat of diagnostic medicine, research, and biotechnology. Let’s take a tour behind the barn doors of the lab. The Fields: Agar Plates and Broth Pastures Every farm needs soil. In the microbe world, our “fields” come in two main forms: solid and liquid. - Agar plates are the lab’s equivalent of neatly plowed plots. Agar, a seaweed-derived gelatin, creates a firm surface where microbes can put down roots—well, ...

Raising Chickens 101: How to Raise Baby Chickens

Tips for Raising Young Chickens in Your Backyard

Want to learn how to raise chicks? Here’s a beginner’s guide to bringing up baby, from purchasing baby chickens to keeping a happy coop.

Where to Get Baby Chickens

There are a number of ways to go about getting chickens! Most often, chicks can be bought locally in the spring, from farm supply stores or small farms themselves. These days, you can even go online to order chicks and get them shipped to your door (or local post office). Then there’s always the “ask a friend with chickens to hatch some for you” approach.

Purchasing Chicks

You can purchase chickens at several stages of development—it all depends on how long you’re willing to wait for eggs.

  • Day-old chicks are available from hatcheries. Most farm suppliers do one or two chick orders a year, so you can get your chickens where you plan to get your feed. They’re usually under $3 each. You’ll have to wait about 6 months for eggs.
  • Ready-to-lay pullets are 20 weeks old and just about to start laying. They’re more expensive than day-olds, but of course, you get your eggs sooner. They can go straight to the coop and are all females. These, too, can be ordered through your farm supplier from the hatchery.
  • Mature laying hens are harder to come by. Unless you have someone with a small flock nearby who wants to replace older hens and will sell their “old girls” to you, chances are, you’ll have to buy pullets or chicks. (“Battery hens” are not good candidates for a farm flock—they’re confined in tiny cages, debeaked, and made to produce so hard that they’re “laid out” at 2 to 3 years of age.)
