What is the Guinea Fowl Sexing Guide Tool?
The Guinea Fowl Sexing Guide Tool helps estimate the sex of young guinea fowl using vent, feather or comb cues. Knowing what you're working with shapes everything from diet and housing to expected size and temperament. That is useful for new owners and shelters alike.
Guinea fowl generally live 10-15 years when they are well looked after. Diet-wise they are an omnivore, which shapes almost every feeding decision you make. Guinea fowl are semi-wild birds kept mainly for tick control and alarm calling. They roam widely, roost in trees given the chance, and are extremely loud, which makes them a poor fit for close neighbors. Keep an eye out for predation while free-ranging, cold injury to feet and wattles, internal parasites. These are the conditions guinea fowl are most commonly seen for.

How does the Guinea Fowl Sexing Guide Tool work?
The result is based on matching the traits you describe against commonly documented characteristics for guinea fowl, not genetic testing. Individual guinea fowl vary more than averages suggest, so read the number as a reference point rather than a measurement.
Factors that matter
- Physical traits such as size: coloring and markings
- Behavioral traits: which can be just as informative as appearance for some questions
- Age: since juvenile traits can differ noticeably from adult ones
- Photo or description quality: the more specific your input, the more useful the match
How do you use the Guinea Fowl Sexing Guide Tool?
- Pick your plumage difference from known males of the species (Brighter or more strongly marked, Duller or more muted, No visible difference)
- Pick your cere color (Blue or bluish, Brown, tan or crusty, Pale, white or pinkish, ...)
- Pick your pelvic bone gap (Narrow, bones nearly touching, Wide enough for a fingertip, Not checked)
- Pick your behavior (Displays, regurgitates, sings elaborately, Shreds paper, seeks dark cavities, has laid an egg, Nothing distinctive)
- Press Calculate, then read the result alongside the sources listed below
Worth doing: jot down the date and the result each time. A single number tells you little, but a trend across a few months tells you a lot about your guinea fowl.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for guinea fowl, but your guinea fowl may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
