Raising turkeys for meat production is a significant part of the poultry industry, with farmers and commercial producers aiming to optimize growth rates to meet market demands efficiently. The time it takes for turkeys to reach market size depends on several factors, including breed, diet, management practices, and the desired weight at processing. This article explores the growth timeline of turkeys, factors influencing their development, and best practices for raising healthy, market-ready birds.

1. Understanding Turkey Growth Rates
Turkeys grow much faster than chickens and other poultry, making them a profitable choice for meat production. The time required for turkeys to reach market size varies based on the following key factors:
A. Breed Differences
Different turkey breeds have varying growth rates:
- Broad-Breasted White: The most common commercial breed, known for rapid growth and large breast muscles. These turkeys typically reach market weight in 14 to 22 weeks.
- Broad-Breasted Bronze: Similar to the Broad-Breasted White but with darker feathers. They grow slightly slower but can still reach market weight within 16 to 24 weeks.
- Heritage Breeds (e.g., Bourbon Red, Narragansett, Royal Palm): These breeds grow more slowly, taking 24 to 30 weeks or more to reach market weight. They are often raised for specialty markets due to their flavor and traditional farming appeal.
B. Market Weight Targets
The desired processing weight influences how long turkeys are raised:
- Fryer-Roaster Turkeys (8–16 lbs): Processed at 12–16 weeks.
- Young Hens (8–16 lbs): Typically processed at 14–16 weeks.
- Young Toms (16–24 lbs): Processed at 16–20 weeks.
- Heavy Toms (24–40+ lbs): May require 20–24 weeks to reach optimal size.
Commercial operations usually process turkeys earlier (14–20 weeks) to maximize feed efficiency, while small-scale or heritage producers may allow longer growth periods for better meat texture and flavor.
2. Growth Phases of Turkeys
Turkey growth can be divided into distinct phases, each requiring specific nutritional and management strategies:
A. Brooding Phase (0–4 Weeks)
- Newly hatched poults (baby turkeys) are highly vulnerable and require controlled temperatures (90–95°F initially, decreasing weekly).
- High-protein starter feed (28–30% protein) supports rapid muscle and skeletal development.
- Mortality rates are highest in this phase, so proper care is essential.
B. Growing Phase (5–12 Weeks)
- Turkeys experience rapid growth, requiring 24–26% protein in their diet.
- Feed intake increases significantly; birds gain 1.5–2 lbs per week.
- Proper ventilation and space (2–3 sq ft per bird) prevent disease and stress.
C. Finishing Phase (13–20+ Weeks)
- Growth slows slightly, but muscle development continues.
- Protein levels can be reduced to 18–20% in the finisher diet.
- Birds are prepared for processing by ensuring proper weight and health.
3. Factors Affecting Turkey Growth Rate
Several elements influence how quickly turkeys reach market size:
A. Nutrition
- High-Protein Feed: Essential for muscle development, especially in the first 12 weeks.
- Balanced Amino Acids: Lysine and methionine are critical for growth.
- Energy-Rich Diet: Carbohydrates and fats support weight gain.
- Feed Availability: Free-choice feeding ensures consistent growth.
B. Genetics
- Commercial hybrids (Broad-Breasted White) grow 30–50% faster than heritage breeds due to selective breeding.
- Slower-growing breeds may have better foraging ability but require more time to reach market weight.
C. Health Management
- Disease Prevention: Vaccinations, biosecurity, and clean housing reduce mortality.
- Parasite Control: Worms and mites can stunt growth.
- Stress Reduction: Overcrowding, extreme temperatures, and poor ventilation slow growth.
D. Environmental Conditions
- Temperature: Poults need warmth; older turkeys thrive at 60–75°F.
- Lighting: Controlled lighting (14–16 hours/day) encourages feeding and growth.
- Space Requirements: Overcrowding leads to aggression and slower growth.
E. Sex Differences
- Toms (Males): Grow larger and faster, reaching 24–40 lbs in 18–24 weeks.
- Hens (Females): Typically processed at 12–20 lbs in 14–18 weeks.
4. Commercial vs. Small-Scale Production Timelines
A. Commercial Turkey Production
- Uses fast-growing hybrids.
- Processed at 14–18 weeks for hens, 18–22 weeks for toms.
- Optimized feed conversion ratios (2.5–3 lbs of feed per lb of weight gain).
- High biosecurity and automated systems maximize efficiency.
B. Small-Scale & Pasture-Raised Turkeys
- Often use slower-growing breeds.
- May take 20–30 weeks to reach market weight.
- Pasture access improves meat quality but slows growth.
- Higher feed costs due to extended growing period.
5. Feed Efficiency and Cost Considerations
- Feed Conversion Ratio (FCR): Modern turkeys convert feed to meat efficiently (2.5:1 to 3:1).
- Total Feed Consumption: A 20-lb tom may eat 75–90 lbs of feed over 18–20 weeks.
- Cost Implications: Faster growth reduces feed costs, making commercial breeds more economical.
6. Processing and Market Readiness
Turkeys are processed when they reach the desired weight and meat quality. Key considerations:
- Live Weight vs. Dressed Weight: A 20-lb live turkey yields 12–14 lbs of meat.
- Meat Quality: Older birds (heritage breeds) have more flavor but tougher meat unless slow-cooked.
- Processing Methods: Small farms may use local processors, while large operations have automated facilities.
Here are 10 frequently asked questions (FAQs) about turkeys, covering their biology, behavior, and cultural significance:
1. What do turkeys eat?
Turkeys are omnivores and eat a varied diet, including seeds, nuts, insects, berries, and small reptiles. Domestic turkeys are often fed commercial poultry feed.
2. How long do turkeys live?
Wild turkeys live 3–5 years on average due to predators, while domesticated turkeys can live up to 10 years if not raised for meat.
3. Why do turkeys gobble?
Male turkeys (toms) gobble to attract females (hens) and establish dominance. They also make other sounds like clucks and purrs.
4. Can turkeys fly?
Wild turkeys can fly short distances (up to 55 mph in bursts) to escape predators, but domesticated turkeys are usually too heavy to fly.
5. What’s the difference between wild and domestic turkeys?
Wild turkeys are leaner, more agile, and have darker meat, while domestic turkeys are bred to be larger with more breast meat and are usually white-feathered.
6. Why are turkeys associated with Thanksgiving?
Turkeys became a Thanksgiving staple in the U.S. due to their abundance in early America and historical references to wildfowl at harvest celebrations.
7. Do turkeys have good eyesight?
Yes! Turkeys have excellent daytime vision (including color perception) and a nearly 360-degree field of view, helping them spot predators.
8. How fast can turkeys run?
Turkeys can run up to 20–25 mph, helping them escape threats.
9. Do turkeys really drown in the rain?
No, this is a myth. While turkeys might look up during rain (possibly leading to water entering their nostrils), they don’t drown from it.
10. Are male and female turkeys different?
Yes! Males (toms) are larger, have colorful wattles and snoods (fleshy face growths), and fan their tails. Females (hens) are smaller and duller in color.
