A young male turkey is called a jake. The term applies from the time a male turkey leaves the poult stage (roughly the first few weeks of life, when all baby turkeys look similar) until he reaches full maturity at about two years old, at which point he earns the title of tom or gobbler. The distinction between a jake and a tom matters to hunters, farmers, and wildlife biologists alike, and the physical and behavioral differences between the two are surprisingly easy to spot once you know what to look for.
Turkey Terminology at a Glance
Turkeys have their own naming system that trips people up because it overlaps with, but doesn’t perfectly match, chicken terminology. A newly hatched turkey of either sex is a poult. Once the birds are old enough to show sex differences, the females are called hens and the males begin their journey from jake to tom. An adult male is a tom (also called a gobbler for obvious reasons), and a group of turkeys is a flock or, in older usage, a rafter. You’ll sometimes hear young females called jennies, though this term is far less common than jake is for young males.
The word “poult” shows up frequently in both farming and research contexts. Studies of domestic turkeys routinely describe their subjects as “male poults” when referring to birds placed into grow-out pens at a young age, regardless of breed or genetic line.1PubMed Central. Performance and processing yield comparisons of Large White male turkeys by genetic lines, sources, and seasonal rearing Once those poults feather out and start showing male secondary characteristics, the jake label kicks in.
How to Tell a Jake From a Tom
If you’re looking at a male turkey in the field and wondering whether it’s a jake or an older tom, several visual cues make the call straightforward.
- Tail fan: A jake’s central tail feathers are noticeably longer than the outer ones, giving the fanned tail a ragged, uneven look. A mature tom’s tail fan is uniform, with all feathers roughly the same length.
- Beard: Jakes grow thin, short beards, usually under about five inches. A tom’s beard is thicker and longer, sometimes reaching nine or ten inches.
- Spurs: This is one of the most reliable aging tools. A jake’s spurs are small nubs, typically under half an inch. Research on wild turkeys has shown that spur length alone can separate harvested males into three age classes: one year old, two years old, and three or older.2Wildlife Society Bulletin. A DEVICE FOR MEASURING SPURS TO ESTIMATE THE AGE OF MALE WILD TURKEYS IN THE SPRING
- Head coloring: Both jakes and toms have the bare, fleshy head characteristic of male turkeys, but a tom’s caruncles (the bumpy growths on the neck and head) and snood (the fleshy projection above the beak) are more developed and change color more dramatically.
- Body size: Toms are simply bigger. Male turkeys continue adding mass well past their first year.
The spur-length method deserves a closer look because it’s the tool that wildlife managers lean on most heavily. When biologists need to assess the age structure of a harvested turkey population, they measure spurs rather than relying on body weight or plumage alone. The visible separations in the frequency distribution of spur lengths across those three age classes make it a practical field technique, not just a lab curiosity.2Wildlife Society Bulletin.

Why Jakes Act Differently Than Toms
The behavioral gap between jakes and toms is driven largely by hormones and social rank. Testosterone levels in male turkeys rise steadily as the bird matures. At around 16 weeks of age, blood testosterone sits at roughly 0.2 ng/mL, then climbs to about 1.3 ng/mL by 34 weeks. That increase tracks closely with testicular growth and the overall march toward sexual maturity.3PubMed.

In behavioral terms, a jake is essentially a teenager. He gobbles, but less frequently and with a higher-pitched, less resonant sound than a mature tom. He struts, but his displays are often clumsy or partial. He’s interested in hens but typically can’t compete with dominant toms for mating access. In wild turkey populations, the social hierarchy among males is strict, and jakes generally sit at the bottom of it.
That hierarchy plays out in some fascinating ways. Among wild Rio Grande turkeys in southern Texas, researchers documented cooperative mating behavior among brothers. Subordinate males assisted dominant siblings during breeding, a strategy that makes evolutionary sense if helping a brother reproduce passes along shared genes even when the helper doesn’t mate directly.5The Auk. Kin Selection in Rio Grande Turkeys: A Critical Assessment Jakes that run in sibling groups may be participating in early versions of these cooperative alliances, though the dominant male in a coalition is usually an older tom rather than a jake.
Growth and Maturation Timeline
Male turkeys take their time growing up compared to females, and the timeline helps explain why the jake-to-tom transition stretches over such a long period. Growth curve research on heritage-type turkeys (American Bronze, specifically) found that males reached their peak growth rate at around 16 weeks of age, while females hit that milestone closer to 13 weeks. Males also took longer overall to approach their mature body weight, which averaged around 9.7 kg (about 21.4 pounds) versus roughly 6 kg (about 13.3 pounds) for females.6Archives of Animal Breeding.

Those numbers represent a heritage breed. Modern commercial turkey lines, particularly the Broad Breasted White birds raised for Thanksgiving tables, have been selectively bred to grow much larger and faster. Commercial toms routinely exceed 40 pounds at processing weight. But even in these heavier birds, males still mature more slowly relative to females, and the biological transition from sexually immature jake to reproductively capable tom follows the same hormonal pathway.
Seasonal timing matters too. In domestic production settings, male poults raised in the fall tend to reach about 2 kg heavier body weights, on average, than birds raised in the spring, likely due to temperature effects on feed conversion and activity levels.1PubMed Central. Performance and processing yield comparisons of Large White male turkeys by genetic lines, sources, and seasonal rearing For wild turkeys, the timing is dictated by hatching season: most poults hatch in late spring or early summer, spend their first fall and winter as jakes, and enter the breeding season the following spring still technically immature. By their second spring, they’ve grown into full toms with the body mass, spur length, and plumage to compete seriously for hens.
The Jake in Turkey Hunting
For hunters, the jake-versus-tom distinction is more than academic trivia. Many states have specific regulations about whether jakes are legal game during spring gobbler season. Some states allow the harvest of any bearded turkey, which includes jakes since most develop at least a short beard by their first spring. Other states discourage or restrict jake harvests to protect the next year’s breeding population.
Hunters learn to distinguish jakes by a combination of the cues described earlier: the uneven tail fan, the shorter beard, and the smaller body. A jake coming to a call often behaves differently too. He tends to approach more eagerly and less cautiously than a wary old tom, which sometimes makes him an easier target but also creates an ethical dilemma for hunters who’d prefer to let the bird mature. The gobble of a jake is often described as scratchy or broken, lacking the deep, rolling resonance that experienced turkey hunters associate with mature toms.
From a wildlife management perspective, moderate jake harvest doesn’t typically threaten population health. Wild turkey populations are polygynous, meaning one tom mates with multiple hens, so removing some young males doesn’t leave hens without breeding partners. But state agencies still monitor age structure in harvested birds using spur measurements and other tools to make sure the population maintains a healthy distribution of age classes.
Do Jakes Ever Successfully Breed?
Yes, though they’re far from first in line. In most wild turkey populations, dominant toms do the vast majority of breeding. Jakes are physiologically capable of producing viable sperm by their first spring, but behavioral dominance hierarchies usually keep them away from receptive hens. The testosterone levels documented in young males show that the reproductive machinery is ramping up well before the bird’s first birthday, with steady hormonal increases from about 16 weeks onward.3PubMed. Correlations of organ weights, hematocrit, and testosterone with sexual maturity of the male turkey
Jakes get their best breeding opportunities in populations where older toms are scarce, whether from heavy hunting pressure, disease, or predation. In those situations, jakes step up and breed successfully. Their fertility isn’t the issue; it’s access. In domestic settings, this is a non-issue since farmers can pair any sexually mature male with hens regardless of age hierarchy.
Domestic Versus Wild Jakes
The term jake applies equally to wild and domestic turkeys, but the practical experience of raising a domestic jake versus observing a wild one is quite different. Domestic turkey breeds, especially the Broad Breasted White, have been selected so heavily for rapid growth that a male poult can reach slaughter weight in as few as 14 to 18 weeks. These birds are harvested long before they’d be considered jakes in any meaningful behavioral sense; they’re still physiologically immature, more poult than jake, even though they may weigh more than a mature wild tom.
Heritage breeds like the Bourbon Red, Narragansett, Standard Bronze, and Royal Palm grow more slowly and live longer, so owners of heritage turkeys actually get to see the jake stage play out. Heritage jakes strut, spar with each other, practice gobbling, and go through the full suite of adolescent male turkey behaviors. Watching a group of heritage jakes figure out the social hierarchy on a small farm is one of the genuine pleasures of keeping turkeys, and it mirrors what happens in wild flocks on a compressed scale.
Wild jakes, meanwhile, spend their first year learning survival skills and social dynamics from the flock. They often stick close to their mother and siblings through their first fall and winter, gradually forming bachelor groups as spring approaches. These bachelor groups, typically composed of siblings and half-siblings, form the basis for the cooperative male coalitions that persist into adulthood and play a role in breeding competition.
Other Poultry and Waterfowl Names for Young Males
Turkey naming conventions sit within a broader tradition of specialized terms for poultry and game birds at different life stages. Young male chickens are cockerels until they reach about a year old, at which point they become roosters (or cocks, in older and British English). Young male ducks are simply called drakes once they develop adult plumage, though some waterfowl enthusiasts use “juvenile drake” for birds in their first year. Young male geese are ganders regardless of age, though “gosling” covers both sexes as hatchlings, much as “poult” does for turkeys.
What makes turkey terminology stand out is that “jake” is specific to turkeys and has no parallel in other domesticated birds. The word’s origin is uncertain, though it likely derives from the same informal use of the name “Jake” that shows up in other American English slang, where it often implies something ordinary or satisfactory. The term has been standard in North American hunting and farming communities for well over a century, and it appears in state game regulations, field guides, and the technical literature without any competing alternatives.
Peafowl, the turkey’s closest commonly kept relative, use yet another system: a young male is a peacock from the moment sex can be determined, though he won’t develop his famous train of display feathers until about three years of age. Guinea fowl have no widely used sex-specific juvenile terms at all, with “keet” covering all young guinea fowl. The specificity of “jake” for turkeys reflects how deeply turkey hunting is embedded in North American culture and how practically important the age distinction is for hunters deciding whether to pull the trigger.
