Early Sexing Challenges (Bucks vs. Hens)

The Ear Test: The Only 100% Method

While humans struggle to see the difference, Guinea Fowl announce their gender through their voices. This usually begins around 8 to 12 weeks of age.

1. The Female Two-Syllable Call

Only the female Guinea Fowl can make a two-syllable sound. It is often described as sounding like the words “Buck-wheat, Buck-wheat!” or “Come-back, Come-back!”  The Pitch: The first syllable is short, and the second is a higher, longer note.

• The Trigger: If a hen is separated from the flock or feels slightly stressed, she will start “Buck-wheating” to find her friends.

2. The Male One-Syllable Shreik

The male is incapable of the “Buck-wheat” sound. He only makes a single-syllable, repetitive sound that sounds like “Chi-chi-chi-chi!” or a sharp, metallic “Keerrr-Keerrr-Keerrr!”

• The Warning: If you have a bird that only ever makes the one-syllable sound, even when separated, it is a male.

The Eye Test: Physical Differences

As the birds mature (after 16 weeks), their “armor” begins to show slight differences. However, be careful – a dominant female can sometimes look like a small male.

Behavioral Clues: The Sultan vs. The Layer

If you spend 15 minutes watching your flock in the evening, the “personalities” will reveal the gender faster than a magnifying glass.

• The Stance (Males): Males walk with their “shoulders” hunched up and their heads held very high. They are the “policemen” of the flock.

• The Aggression: If two birds are facing off, chest-to-chest, jumping and pecking at each other’s heads, they are almost certainly two males fighting for dominance.

• The Lead (Females): When moving to food or the coop, the females are often in the lead, while the males bring up the rear or patrol the flanks to watch for predators.

Technical Method: Vent Sexing

This is the method used by professional hatcheries, but it is very difficult for beginners and can injure the bird if done incorrectly.

• The Process: It involves gently everted the “vent” (cloaca) of a 12-week-old bird to look for a small “phallus.”

• The Verdict: Unless you have been trained by a vet or an experienced breeder, avoid this. It is much easier (and safer) to just wait for them to start talking!

Local Case Study: The Noisy Night in Karatina

A farmer named Njuguna bought 20 “guaranteed females” from a traveling trader to start an egg business. He spent 4 months feeding them high-quality grower mash.

• The Problem: As they matured, the noise became unbearable. The birds were fighting constantly, and not a single egg was laid.

• The Discovery: Njuguna separated the birds one by one into a small cage. He realized that 18 out of the 20 birds were only making the “Chi-chi-chi” sound. He had been sold a “surplus male” batch.

• The Fix: He slaughtered 17 of the males and sold the premium meat to a local hotel for 2,500 KES each. He used that money to buy 15 confirmed “Buck-wheating” hens from a reputable breeder.

• The Lesson: Never buy “un-sexed” mature birds based on physical looks alone. Always ask the seller to let you hear them “call” before you pay.

Important Things to Keep in Mind

• The Imposter Hen: Occasionally, a very young male might try to imitate the “Buck-wheat” sound, but it will sound “cracked” or weak. Trust the consistent, loud calls.

• Isolation is Key: To sex a bird accurately, take it 20 meters away from the flock. The “loneliness” will force the bird to use its gender-specific call to find the others.

• Marking Your Progress: As soon as you identify a bird’s sex, use different colored leg bands (e.g., Blue for Boys, Red for Girls). This prevents you from having to “re-sex” the same bird twice.

• The Quiet Bird: Some birds are naturally shy. If a bird stays silent for 30 minutes during isolation, put it back and try again two weeks later.
