The Cornish Cross Chicken breed, also called the Cornish Rock, is widely popular in the poultry industry.
While they sound similar, Cornish Chickens and Cornish Cross Chickens are different breeds. The Cornish Chicken is a heritage breed. The Cornish Cross Chicken is a cross-breed that we will discuss in the history of this popular meat bird.
Whenever someone mentions a “broiler bird,” the Cornish Cross chicken is typically the bird they are referring to. Without this popular breed, we wouldn’t have quite the large poultry industry we have today.
Several qualities make this breed unique, including their fast growth time, meat quality, and usage in crossbreeding.
This blog post dives into the many characteristics of this breed, exploring its origins, identifying features, and the unique advantages of using these birds for market.
If you’re interested in learning more about this magnificent breed and its effect on the poultry industry, then you came to the right place!

When it comes to the origins of the Cornish Cross chicken, there’s quite a story behind it. It started with the 1948 Chicken of Tomorrow Contest, where the goal was to create a bird that would grow larger, faster, and hold weight in all the right places.
The 1948 “Chicken of Tomorrow contest” first runner-up was a White Plymouth Rock chicken bred by Henry Saglio from Connecticut. One of the other top broilers was a Red Cornish crossed with a New Hampshire Red from Vantress Hatchery.
This bird was created through selective breeding between the Cornish Chicken, known for its meat quality and compact body shape, and the White Plymouth Rock chicken, a fast-growing, robust chicken breed.
The end goal when developing the Cornish Cross chicken breed was to create a meaty bird with rapid growth rates, and this bird did just that.
Over the years, breeders have fine-tuned these birds to shave off growth time while building more muscle. Without this breed, the commercial poultry industry would not be what it is today.
While they have taken the meat industry by storm, they are a less common breed for backyard flocks. However, if you want to raise these birds, they are not impossible to come by!
When it comes to the Cornish Cross chicken breed, there are three different main commercial lines, which are the Cobb 500, the Ross 308, and the Ross 708.
All three of these strains have the same look to them. They are round, plump birds with white feathers, yellow legs and skin, and single red combs. However, the Ross 708 is more of an evenly weight-distributed bird instead of being breast-heavy like the rest.
It is important to remember that this breed is raised for commercial meat production. Therefore, Cornish Cross chickens’ bodies are large and round. At maturity, they average 6 to 8 pounds.
The Cornish Cross chicken breed has been bred to reach maturity quickly and reach market weight and maturity as fast as possible. Most Cornish Cross Chickens are butchered at around eight weeks.
Much like most chicken breeds, when it comes to the difference between the roosters and hens, the roosters tend to be larger and more robust than the hens.
Since the Cornish Cross Chicken are bred for their meat quality, there are few differences between the males and females. Getting to market size fast is the purpose of their breeding rather than distinct appearance differences between the sexes.
Ensuring that they are docile is essential when raising birds in large quantities. The Cornish Cross chicken is just that. They aren’t overly focused on pecking order. They are very social and docile birds.
Despite being docile birds, overcrowding can cause aggressive behavior. Make sure that they have enough space!
This breed is known to be way less active when compared to other chicken breeds. You can let them free-range more successfully if you follow specific guidelines. However, free-ranging is optional when raising Cornish Cross chickens.
These birds focus on one main thing-eating and eating and more eating.
Due to their large body shapes and laidback personalities, other chicken breeds within your flock may bully them. Therefore, you’ll want to ensure that you keep an eye on them.
Since Cornish Cross chickens have been genetically bred to gain weight as fast as possible, these birds can eat. Seriously, THEY CAN EAT.
One of the main things these birds need is protein. Protein helps build muscle, and they will rapidly be doing that. During their starter phase of life, their feed contents should be about 22-23% protein. You can reduce protein to 18-20% in their grower phase.
Your birds are going to need a diet with balanced carbohydrates and fats so that they can have enough energy throughout the day.
One of the most crucial ingredients in their diet is calcium. Their body grows astonishingly, and they need calcium so their bones can hold all the muscles.
Generally, for each pound they gain, Cornish Cross chickens and other broiler chickens eat about 2 lbs.
Access to clean, fresh water is necessary for their digestive health; they will eat a lot and need a lot of water.
Remember, your Cornish Cross’ nutritional needs can depend on several factors, including if you want to raise them for meat or just as an addition to your flock.
Housing and Space Requirements
Providing adequate space and housing for your Cornish Cross Chickens is essential for their health and well-being.
Cornish Cross chickens need an adequate amount of space per bird. A standard coop sizing guideline for these hens and roosters is at least two square feet per bird.
With any chicken coop design, you’ll want to ensure proper ventilation. These birds will do a lot of sitting, thus leading to litter buildup. You’ll want as little moisture buildup as possible so that it won’t lead to respiratory problems.
They tend to be way less cold-hardy than most chicken breeds. So, you must properly maintain heating measures during harsher winter. If you need help with ways to ensure your Chickens’ well-being in the winter, you can always check out our article here.
They are also not very heat tolerant. These hens are prone to heat stress; providing water and shade is crucial for their well-being.
Continuous low lights are recommended for your coop when raising broiler chickens, like the Cornish Cross. Phillip Clauer, Former Associate Teaching Professor, 4-H Youth, and Poultry Coordinator, suggests that you “Provide one 25-40 watt bulb per 100 sq. feet.”
Health and Well-being
As with any poultry breed, Cornish Cross chickens come with common health issues. However, their rapid growth rate can make them more susceptible to these health issues.
Respiratory Problems Cornish Cross chickens can be more susceptible to respiratory issues because of their fast growth. It’s essential to watch for infections such as mycoplasma and viral infections. Good hygiene and ventilation practices are important to combat these issues.
Leg Problems Their rapid growth leads to leg problems and deformities, including lameness and splayed legs. Maintaining a proper diet and managing your backyard chickens’ growth rate is crucial for their well-being.
Heart and Cardiovascular Issues Their fast growth rates can strain their hearts and lead to cardiovascular problems. To combat this, you’ll want to ensure they have a balanced diet, manage their weight, and monitor for signs of distress.
Signs of a happy, healthy Cornish Cross Chicken include but are not limited to:
- Active and alert behavior.
- Smooth, clean feathers.
- Clear and bright eyes. (Mareks Disease)
- Good appetite and hydration
- No signs of respiratory distress (e.g., coughing, sneezing, nasal discharge).
- Proper body weight and mobility.
- No signs of leg deformities
Pros and Cons of Raising Cornish Cross Chickens
With any other chicken breed, there are pros and cons to raising Cornish Cross chickens.
Fast Growth Rate: If there is one thing that the Cornish Cross is known for, it is its rapid growth rate. They reach market weight in an astonishing 6-8 weeks. This swift turnaround is essential for those seeking meat production efficiency.
High Meat yield: They quickly grow and have a high bone-to-meat ratio. This means you get more meat from each bird than other chicken breeds.
Feed Conversion: One of the most incredible things about these birds is their feed conversion abilities. Birds raised for the Commercial Industry are said to have a 2:1 conversion ratio. While the average backyard flock is closer to 3.5:1. This is crucial for profit potential.
Specialized Diet: Since these birds will gorge themselves to death if given the opportunity, you will want to put them on a specialized diet with a strict feeding schedule.
Health issues: While their growth rate is incredible, it can lead to several health issues. Sometimes, their body can’t keep up with how fast they are growing. Unfortunately, this means this breed experiences higher mortality rates than most other breeds. As well as they tend to have additional structural issues, including leg issues.
Egg Production: Because these birds are meat birds, they are not good egg layers. They tend not to be very broody. And it’s not uncommon for them to have trouble laying eggs because of their size.
Ultimately, it truly depends on your priorities and goals whether raising this breed is a good fit for you. If you want a bird proficient at gaining weight for market, they are the bird for you. However, if you’re looking for an active bird that will give you lots of eggs, there are better choices than the Cornish Cross.
Suppose you want to raise Cornish Cross Chickens for market. In that case, you’ll be pleased to know that their rapid growth time tends to cost you less because of lower overall feed costs than slower-growing breeds that require more time and resources to reach the same market weight.
While the market for Cornish Cross chickens can be competitive, there is always a high demand for their white tender meat, and there will always be this demand.
The economic considerations for raising Cornish Cross chickens depend on many factors, including your specific intentions for raising them, resources, and current market conditions. While they offer advantages in rapid growth and efficient meat production, there are also potential setbacks related to health issues and ethical concerns.
