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.
