Jumbo Cornish Cross chickens were first developed for commercial meat production, and for the last fifty years, no other breed has been able to compare. The reason the Jumbo Cornish Cross has dominated so effectively is because this breed has the ability to grow much quicker than any other. If you are someone who is looking to raise chickens for meat purposes, you truly cannot do better than the Jumbo Cornish Cross chicken, and Chickens for Backyards can help supply you with the chicks you need to fill your freezer.

Most Jumbo Cornish Cross chickens will grow to be about 5 or 6 pounds after just 7 or 8 weeks before eventually averaging out between 6 and 10 pounds when fully grown. Outside of growing quickly, they are also known for their excellent feed efficiency; as they only need to consume about 12 to 14 pounds of feed each to achieve projected results. This is why so many families raise Jumbo Cornish Cross chickens for their meat.

Because the Jumbo Cornish Cross chicks grow so fast, they are susceptible to a number of health issues and can struggle with balance and movement when they hit just 10 weeks of age and we highly recommend that this particular chicken breed not be kept as a pet. It’s better to choose a different breed if your goal is to keep a chicken as a pet in your backyard. However, for those who want Jumbo Cornish Cross chickens purely for processing reasons, Chickens for Backyards is happy to supply these chicks for sale.

Provide full feed the first 5 days, then feed 12 hours on and 12 hours off.

  1. Best Meat Chickens I have ever Grown!

    I have been raising Cornish Rock Crosses Yearly for the last 10 years. I ordered these birds last year for the frist time. They were the best chickens I have raised. Fast growing, No health problems, and are so tender, juicy and flavourfull and I fed them the same and raised them the same as all of the other chickens I had gotten at other hatcheries. I wont order from anywhere else again!
