Raising chickens for meat involves first deciding which to choose: Cornish broilers or a heritage breed. The fundamental difference is the amount of time needed to grow them from hatch to harvest. The quicker they grow to the target weight of about six pounds, the cheaper they are to raise and the more tender the meat. The longer they grow, the more flavorful the meat. Let’s take a closer look at specific differences.
White Cornish Hybrids
The most efficient meat chickens are an industrial creation developed by combining white Cornish and white Plymouth Rock genetics. The resulting Cornish cross broilers are the chickens you’ll most likely find in the meat department at the supermarket. Cornish cross broilers share these 10 characteristics:
• They grow and feather rapidly.
• Chicks of the same age and sex grow at the same rate.
• They consume about 2 pounds of feed per pound of weight gained.
• They reach a weight of 6 pounds in 6 to 7 weeks.
• The edible portion is approximately 75% of live weight.
• They have white feathers for clean picking.
• They have fewer feathers to pick and no hairs to singe.
• They are broad breasted, producing mostly white meat.
• Leg and breast meat cook at the same rate.
• The meat is soft and bland.
A significant feature of Cornish hybrids is that they must be butchered as soon as they reach target weight. Otherwise, as a result of their excessively rapid growth, they begin to develop bone ailments and heart failure.
Cornish broilers can be encouraged to forage if introduced to pasture no later than three weeks of age. The energy used while foraging somewhat slows their growth, making them a little less susceptible to leg problems. On the other hand, their white plumage and minimal activity make them vulnerable to predation.
Before Cornish broilers were developed, heritage breed roosters were traditionally raised for meat. Because of their slower rate of growth, they do not experience the same leg and heart issues.
Heritage chickens are instinctive foragers, making them ideal for free ranging. Access to grass results in meat with more omega-3s and other healthful nutrients. And their colored plumage and greater activity lets them more easily evade predators. Here are 10 more characteristics shared by heritage breeds:
• They grow and feather rather slowly.
• Some chicks grow more slowly than others.
• They consume about 4 pounds of feed per pound of weight gained.
• They reach a weight of 6 pounds in 16 weeks or more.
• Their colored feathers and hairs are time consuming to pick clean.
• The edible portion is approximately 65% of live weight.
• They produce more dark meat and less white meat.
• The meat is lower in fat and firmer in texture.
• Breast meat cooks faster than leg meat.
• The meat is firm and flavorful.
If you have never enjoyed the meat of heritage cockerels, you don’t know what real chicken tastes like.
