Heritage breeds such as the Rhode Island reds are much different from the packaged chicken you bring home from the grocery store. 

Even the so called "dual-purpose" breeds - those that are supposed to be good producers of both eggs and meat - aren't the same as bred-for-the-table birds.

While some folk say that those white "Frankenstein" chickens that are grown solely for meat are genetically modified (GMO), they aren't - they're simply bred for super-fast growth. 

Let's be honest, chickens reach maturity between four and six months of age, and their eggs hatch after just 21 days, so it doesn't take long at all to see the results of your breeding plans. Several generations of birds can be tracked within a relatively short period of time. 

Compare that to goats, cows and horses (not to eat, of course!), where you have to invest several years before an animal is old enough to be bred, carries the baby to birth, and the next generation grows up to be bred again. 

It takes much longer to evaluate the results of your breeding program and to change the characteristics of large mammals.

The neatly-packaged chicken you bring home from the grocery store are usually white chickens called Cornish cross or Cornish Rock cross. 

These birds are a cross between the white Cornish and White Rock breeds. Some hatcheries might give them a different name, but they are basically the same birds.

Our Rhode Island red cockerels, and other dual-purpose breeds like them, take longer to reach butcher size. They are a bit tougher to eat, but they are still very good. 

They are best cooked slow and moist: stewed on the stove-top, cooked in the slow cooker or pressure cooker. I'm told they are very good in the smoker too.

Aside from taste and texture, one of the biggest differences between heritage breeds and Cornish cross chickens is the amount of time it takes to grow them out. 

Heritage breeds take about five months to reach butcher size, while Cornish cross birds are ready to butcher at about 8-10 weeks of age.

You read that right. Just weeks. Cornish cross are ready to butcher in two or two-and-a-half months.

Basically the heritage breeds take roughly twice as long to grow out, which means they require approximately twice as much feed and twice as much labor. 

You can free-range your heritage birds so that they're foraging for some of their food as well as earning their keep by eating bugs, but you're still feeding them twice as long as the Cornish cross chicks.

The Cornish cross chickens aren't interested in exercise and aren't good foragers. They like to wait in front of the feeders until you bring them more feed.

We don't have running water near the poultry coops, so I had to carry water to the Rhode Island reds for twice as long as I did to the Cornish cross.

Since the Cornish cross chicks tend to stand in front of the feeders all day long and eat, eat, and eat some more, they also produce a great deal more droppings. I find their droppings to be much wetter, heavier and smellier. 

Their coop needs to be cleaned much more often. On the other hand, there's a greater quantity of droppings to add to the compost pile too.

Cornish cross birds are likely to have leg problems because they are so heavy. They are also prone to heart attacks for the same reason. 

Meat birds will give you a greater yield after butchering. I compared the final weight of our Rhode Island reds with our Cornish cross chickens in another post, Raising Cornish Cross Chickens.

Heritage breeds:

• take 4-5 months to reach butcher size
• have tougher meat
• produce less meat
• must be fed for a longer period of time
• are better foragers

Cornish Cross:

• reach butcher size in just 8-10 weeks
• produce tender meat
• are heavier/meatier
• consume more feed
• aren't good foragers
• produce wetter droppings in greater quantity; it's harder to keep them clean
• are smelly

So, is one type of chicken better to raise for meat than the other? 

They both have their pros and cons, and the final decision is up to you. 

You might prefer to incubate your layer hens' eggs and process the extra rooster chicks when they are old enough, or you might want to buy Cornish cross chicks and raise a year's supply of meat at once.
