Click here to view as a pdf: Field Trial Comparing Jumbo Cornish Cross and Red Rangers Using Crystal Creek® Broiler Feed
By Ryan Leiterman, D.V.M.
Raising meat chickens is an increasingly popular practice among homesteaders seeking greater food independence, control over production inputs, and fresher, more flavorful protein. This field trial compared the Jumbo Cornish Cross, a fast-growing, high-efficiency commercial broiler, with the Red Ranger, a slower, more active, and pasture-adapted type. Both were raised on Crystal Creek® Broiler Feed to evaluate growth rate, feed conversion, carcass yield, health outcomes, and cost efficiency under typical homestead conditions.
The Cornish Cross is a hybrid designed for rapid growth and high breast yield, often reaching 6–7 lbs live weight in as little as six weeks. The Red Ranger, also known as the Freedom Ranger or Rudd Ranger, grows more moderately and is known for its ability to thrive on pasture, producing leaner, darker meat with stronger flavor. While the Cornish Cross offers superior feed conversion and processing yield, it is less resilient in heat and less suited to free-range life. The Red Ranger, though slower to finish, offers better adaptability, vigor, and bird welfare.
Methods
Two groups of straight-run chicks from Abendroth Hatchery were started on the same day. The Cornish Cross group (115 chicks) was raised indoors on pine shavings with gravity feeders, waterers, and free-choice Crystal Creek® Broiler Feed. The Red Ranger group (20 chicks) was raised in a coop with fenced pasture access containing mixed grasses and clover. Cornish roosters were processed at seven weeks, hens at nine weeks, and Red Rangers at eleven weeks.
The trial took place during summer in Wisconsin, with daytime highs exceeding 90°F on several days.
Cornish Cross As Babies
Feed was provided from start to finish using the same ration to standardize input and evaluate breed response to Crystal Creek® Broiler Feed, which is a complete, balanced formulation designed for steady growth, efficient feed conversion, and consistent carcass quality. Water was provided continuously for both groups, and bedding or pasture areas were kept clean and dry.
Results
Cornish Cross roosters averaged 11 lbs live weight at seven weeks, hens averaged 10 lbs at nine weeks, and Red Rangers averaged 6 lbs at eleven weeks. Dressing percentages were 73% for Cornish Cross and 67% for Red Rangers. The Cornish Cross group consumed 1,760 lbs of feed (approximately 17 lbs per bird), while the Red Rangers consumed 320 lbs (about 16 lbs per bird). Mortality was 8.7% in the Cornish Cross group (10 birds lost to heat or disease) and 5% in the Red Ranger group (1 bird lost to predation).
Cornish Cross carcasses were broad-breasted and mild-flavored, while Red Rangers yielded leaner, darker meat with firmer texture and richer flavor. The Cornish Cross group achieved an estimated feed conversion ratio (FCR) of 1.87, while Red Rangers had an FCR of 2.35.
Cost Analysis
Cornish Cross:
115 chicks ($247.25) + feed ($825.00) = total $1,072.25.
With 105 processed birds averaging 7.6 lbs carcass weight, total yield was 798 lbs, for a cost of $1.34 per pound.
Red Ranger:
20 chicks ($92.00) + feed ($150.00) = total $242.00.
With 19 birds processed averaging 4.0 lbs carcass weight, total yield was 76 lbs, for a cost of $3.18 per pound.
Although the Cornish Cross was more efficient, the Red Rangers may offer a market advantage if sold as pasture-raised or heritage-type meat, which often commands a higher retail price.

Discussion
The Cornish Cross excelled in growth speed and feed efficiency but was more vulnerable to heat stress and disease. Red Rangers grew more slowly yet thrived in outdoor conditions, showing strong health and minimal losses. Their leaner carcasses and rich flavor suit pasture-based systems and premium markets. For homesteaders prioritizing efficiency, Cornish Cross is unmatched; for resilience and sustainability, Red Rangers are preferable.
Management differences also played a key role: indoor confinement favored feed efficiency but demanded more environmental control, while pasture access improved welfare and flavor but required more time and feed. Both breeds responded well to the Crystal Creek® Broiler Feed, indicating that its balanced nutrition supports steady, healthy growth across varied production systems.

Conclusion
Using Crystal Creek® Broiler Feed, Cornish Crosses reached up to 11 lbs live weight in seven weeks, while Red Rangers reached 6 lbs in eleven weeks. Cornish birds achieved higher yields and lower cost per pound but required closer environmental control. Red Rangers demonstrated superior adaptability, flavor, and hardiness.
For homesteaders focused on quick, cost-effective production, the Cornish Cross remains unmatched. For those prioritizing resilience, flavor, and sustainable management, the Red Ranger represents a robust and rewarding alternative. The key takeaway: breed choice should match management style and homestead goals.
