Check comb and wattles: males usually develop larger, redder combs and wattles earlier
Check feather shape: males often have longer, pointed hackle and saddle feathers; females usually have rounded feathers
Check tail feathers: males may develop curved sickle feathers; females usually have shorter, straighter tails
Check leg size and stance: males are often thicker-legged and stand more upright
Check behavior: males may crow, spar, and act more dominant
Check spur development: males typically develop spurs on the legs
Check egg laying: females will lay eggs once mature
Use vent sexing only if trained: it is difficult and can injure the chick if done incorrectly
Use DNA sexing for accuracy: a lab test can determine sex from a feather or blood sample
Ask a breeder or veterinarian: they can help identify sex more reliably
