The best feed for the Cornish chicken breed is a high-protein starter and grower feed, such as Purina Start & Grow or Manna Pro Nutrena, because Cornish chickens are bred for rapid growth and muscle development. These feeds provide the essential nutrients and amino acids to support their fast growth rate while maintaining overall health and meat quality.
What to Look For
When selecting feed for Cornish chickens, focus on key nutritional components that support their unique growth needs. First, protein content is critical; Cornish breeds require a diet starting with 20-24% protein during their starter phase and then about 18-20% in the grower phase to develop their muscular build efficiently. Second, energy levels from carbohydrates and fats must be balanced to fuel their rapid growth without causing excess fat accumulation. Third, vitamins and minerals like calcium, phosphorus, and vitamin D are vital for bone strength, especially since Cornish chickens are prone to leg problems if their diet is deficient.
Additionally, feed form matters: crumble or pellet feeds are preferred for easier consumption and less waste. Avoid feeds with excessive fillers or artificial additives, as these can impair growth and health. Lastly, consider the feed’s suitability for your bird’s age and purpose—starter feed for chicks, grower feed for juveniles, and finisher feed if raising for meat production.
Purina Start & Grow
Strengths: Purina Start & Grow is a widely available, well-balanced feed formulated to support broiler-type chickens like Cornish breeds. It has a high protein content (20-24%) ideal for chicks and growing birds, with added vitamins and minerals for strong bone development. Its crumble form is easy for young chicks to eat, and it has a proven track record in commercial and backyard settings.
Trade-offs: This feed can be pricier than generic options, and it contains some ingredients like soybean meal and corn that may not be organic or non-GMO. Also, it is a general starter feed, so it may require switching to another grower or finisher feed as birds mature.
Best for: Owners who want a reliable, readily available feed with a solid nutrient profile for Cornish chicks and growers, especially if raising birds for meat or show.
Manna Pro Nutrena NatureWise Range
Strengths: Nutrena NatureWise offers non-GMO and all-natural ingredient options, with a starter feed containing around 22% protein. It supports healthy growth and immune function with added probiotics and vitamins. The pellet form reduces feed waste and encourages consistent intake.
Trade-offs: The price point is generally higher than standard feeds, and availability can be limited depending on location. The natural formula may lead to slightly slower growth compared to feeds with added synthetic amino acids.
Best for: Cornish chicken owners focused on organic or natural feeding practices who want to avoid synthetic additives but still need a high-protein diet for their birds.
Scratch and Peck Feeds Organic Starter
Strengths: Scratch and Peck Feeds provides a certified organic, non-GMO starter feed with around 20% protein from whole grains and legumes. It is minimally processed, free from synthetic chemicals, and includes flaxseed for omega-3 fatty acids, which can improve meat quality and bird health.
Trade-offs: The feed is more expensive than conventional options and may require supplementing with additional calcium for optimal bone growth. Also, its coarser texture might be less palatable to some chicks initially.
Best for: Owners prioritizing organic certification and sustainable sourcing who are willing to invest more for cleaner ingredients and health benefits.
Purina Layena (for mature Cornish hens)
Strengths: While Cornish chickens are often raised for meat, some keepers maintain layers from this breed. Purina Layena is formulated with balanced protein (16-18%) and higher calcium for strong eggshells, making it suitable for adult birds transitioning from grower feeds.
Trade-offs: Layena is not intended for rapid growth phases and has lower protein than starter or grower feeds. It also may cause Cornish birds to gain more fat if used too early or exclusively.
Best for: Keepers with mature Cornish hens who want to maintain egg production with a nutritionally balanced feed.
Scratch Grains Mixes (Supplemental)
Strengths: Scratch grains can be an excellent supplement for Cornish chickens, providing variety and encouraging natural foraging behavior. They add energy and some protein but should never replace formulated feed during growth phases.
Trade-offs: Scratch grains are low in essential amino acids and vitamins, so overfeeding can lead to nutritional imbalances and slow growth. They also encourage selective feeding, which can cause feed waste.
Best for: Owners who want to add enrichment and variety to their Cornish chickens’ diet but understand the importance of balanced formulated feed as the primary source of nutrition.
How to Choose
Choosing the right feed for your Cornish chickens depends on your budget, your birds’ purpose (meat production, show, or dual-purpose), and your feeding philosophy (conventional vs. organic/natural). If you are raising Cornish chickens for meat, prioritize high-protein starter and grower feeds like Purina Start & Grow or Nutrena to achieve rapid, healthy muscle development. These tend to be cost-effective and widely available.
If you prefer organic or non-GMO feeds and are willing to invest more, options like Scratch and Peck or Nutrena NatureWise offer cleaner ingredients with slightly slower but still healthy growth. For mature birds kept for eggs, switching to a layer feed like Purina Layena ensures proper calcium intake without excessive protein.
Budget-conscious keepers might start with a high-quality starter feed and supplement with scratch grains or kitchen scraps to reduce costs but must monitor their birds’ growth and health closely. Always avoid feeds with too low protein or excessive fillers, as Cornish chickens need nutrient-dense diets to avoid leg issues and poor muscle formation.
Frequently Asked Questions
Q: Can I feed regular layer feed to Cornish broilers?
Layer feed has lower protein and higher calcium, which is not ideal for growing Cornish broilers. Use starter and grower feeds during growth phases, then layer feed only if keeping hens for eggs.
Q: How long should I feed starter and grower feed?
Typically, feed starter from day 1 to 6 weeks, then switch to grower feed until 12 weeks. After that, finisher or maintenance feed can be used depending on your goals.
Q: Is it necessary to use medicated feed for Cornish chicks?
Medicated feed helps prevent coccidiosis in young chicks but is not mandatory if you practice good hygiene and biosecurity. Consult a vet if unsure.
Q: Can Cornish chickens eat treats or kitchen scraps?
Yes, but treats should be limited to less than 10% of the diet to avoid nutrient imbalances. Avoid salty, sugary, or moldy foods.
Q: What protein percentage is best for Cornish chickens?
20-24% protein for starters and about 18-20% for growers is ideal to support rapid muscle growth without excess fat.
Q: Should I give supplements like calcium or vitamins?
If feeding a balanced commercial feed, additional supplements usually aren’t necessary. However, if birds show signs of deficiency or you feed scratch grains heavily, supplements may help.
Bottom Line
For Cornish chickens, the top feed choice is a high-protein starter and grower feed like Purina Start & Grow because it meets the breed’s rapid growth and muscle development needs effectively. If you prefer natural or organic options, Manna Pro Nutrena NatureWise or Scratch and Peck Organic Starter are excellent alternatives but come at a higher cost. Always prioritize protein content and nutrient balance over price alone, and adjust feed type as your birds mature. With the right feed, your Cornish chickens will thrive, whether raised for meat, show, or eggs.
