JUVENILE CHICKEN SEXING: SINGLE COMB SEXING
Breeds include: Ayam Cemani, Barnevelder, Barred Plymouth Rock, Bielefelder, Cream Legbar, Frizzle Cochin, Orpington, Marans, Rhode Island, Salmon Faverolle, Sussex
Combs are absent as newborns. Cockerels’ combs develop faster and often begin to redden as early as 3 weeks of age. Around 5-6 weeks of age, their comb becomes a nice big red flag making claim of being a male. As pullets develop combs, they appear yellowish orange. Pullet combs will turn bright red closer to point of lay. Comb sexing at 5-6 weeks of age works best if you have multiples of the same breed to compare and contrast the developmental differences.
Note: Ayam Cemani and Onyx Sundance single combs remain black. Thus, you can only judge by the size of comb and not the color.
