Jumbo Cornish X Rocks
Jumbo Cornish Cross Broiler Chicken
Jumbo Cornish X Rocks (Cornish X), (Cornish –Cross), (Broiler), (Cornish/rock), (Jumbo Cornish cross) is a cross between the Commercial Cornish chicken and a White Rock chicken. They were developed for the commercial meat chicken market and have been dominating it for the past fifty years. Cornish game hens for sale can reach 4 1/2 lbs by 6 weeks of age and cockerels 6 lbs by 6 weeks of age. They grow so fast that their legs may give out from their weight and it is not recommended that they be kept for breeding. You can take away the chicken feed at night to restrict the feed intake to slow the growth of the chicken.
This will allow the bones and tendons to catch up with the rapid growth of the Cornish broiler or as some call a game hen. However, do not use small particle bedding (like saw dust or small shavings) because when restricting their feed they will eat too much of their bedding material and cause sickness and death. This breed is bred specifically to butcher or harvest and is not recommended for a pet and only as chickens for meat production. Generally, if the Cornish broiler chicken is NOT butchered or dressed it will have health issues with the heart, bones, muscles, tendon and sores from sitting all the time.
This breed is your best option for efficient feed/time to butcher weight and is the best choice for raising chickens for meat. Global Poultry Co. Ltd® currently hatches the “Ross 308” blood line/strain. It is recommended to harvest this chicken broiler between 4-10 weeks of age depending on desired weight. It takes roughly 14 lbs of feed to get 1 chick to 8 weeks of age. At 8 weeks the expected average weight (averaging for male and female) is 6 ½ pounds of live weight.
Raise these chickens in a free range chicken coop and try out your best chicken recipe for your family. Feed high protein feed that is 21% or better. Fluid in the body cavity (Ascites) and/or leg weakness may result and it may be necessary to restrict the feed intake – slowing down the growth rate. Note: The Cornish broiler may not do well if you are in a high elevation in the USA. They will be more prone to heart attacks and health issues at high altitudes, so please take this into consideration before ordering them.

Should you raise Cornish Cross chickens for meat?
If the desire to be more self-sufficient has you thinking about raising broiler chickens, you’re not alone.
Raising chickens for meat has become quite popular in the past year or two, and hatcheries have had trouble keeping up with the demand for these meat birds.
We’ve raised chickens for meat before, both Rhode Island red chickens – which are a dual-purpose breed for both the table and for egg-laying – and Cornish Cross chickens, a breed developed especially for the freezer.
What will you feed your meat chickens?
Meat birds eat a lot. Our fifty birds at six weeks of age are eating two 50-pound bags of feed per week. That will continue to increase as they get larger.
Their high-protein feed is more expensive than other chicken feed. Be sure to budget for this expense.
You can keep costs down a bit though. Letting your meat chickens free range, or using a chicken tractor that you move around the yard will cut your feed costs a bit, but Cornish Cross chickens don’t move around much and prefer to sit in front of the feeder and eat. And eat. And eat.
When your birds get larger, you should remove their feeder overnight to help keep them from gaining weight too fast.
You’ll need enough feeders so that all of the broilers will be able to reach the feed. Since Cornish cross like to sit in front of the feeders, make sure all of the birds have ample access to food.
