Silkies can be quite late to mature (perhaps as much as 8 or 9 months old). Because they
take so long to develop it is very hard to know if your silkie chicks are cockerels or pullets, particularly if
they are not from the same genetic line. Silkie cockerels tend to be bigger in size and the comb will usually
develop sooner than on a pullet but the first more obvious sign is at around 4-6 months when their hackles start
to develop ’streamers’. Even so it is often not 100% certain until they begin to crow or lay an egg.

Information on Sexing Silkie Chickens
Source: Silkie chickens are unusual-looking birds with feathers that resemble silk or fur. These fluffy creatures
have crests or topknots on their heads, and extensive feathering down their entire leg and part of the foot. They
also have five toes instead of the standard four. According to the American Silkie Bantam Club, these chickens are
mentioned as far back as the the 13th century, in the writings of Marco Polo. However, male silkie chickens can be
difficult to tell from females.
Silkie chickens take longer to mature than many other chicken breeds--as much as eight to nine
months. Unlike sex-link chicken breeds and chickens bred to be feather-sexed, silkie chickens show
few difference before they reach maturity. According to the American Sikie Bantam Club, experienced
silkie owners develop ways to identify the sex of their chicks by about eight to 12 weeks, but can
be wrong as much as 50 percent of the time.
Male silkie chickens, or cockerels, are usually larger than the females, or pullets, even at a
young age. Males also usually have larger, quicker-developing combs, a swept-back crest and larger,
rounder wattles. Males tend to develop spurs, and will have longer, more pointed feathers around
the neck, or hackle, and just in front of the tail. In some cockerels, the saddle feathers in front
of the tail may slightly cover the wings. Males also tend to have less fluffy, more pointed
All breeds of chickens, including silkies, can be vent-sexed. This method involves inverting the
chicken and examining its cloaca, or vent, for male sex organs. According to Chicken Crossing,
experienced workers have around a 95 percent success rate sexing chickens through the vent.
Amateurs who've just learned the basics are usually no more accurate than 60 to 70 percent. For the
most accurate assessment, silkie owners should get in touch with a professional, such as an avian
Sexing silkie chickens via external characteristics isn't always effective, even for the most
experienced chicken owner. Silkies with all the characteristics of males, including a tendency to
crow in the morning, have been known to suddenly lay eggs. Cases like this are unusual, but
demonstrate variability among individual animals. A silkie may be nearly a year old
before it displays its gender.
Despite their attractive appearance and docile personality, silkies aren't the ideal chicken for
all situations. Silkie chicken owners should be aware that sexing these birds can be difficult and
inexact, even when done by professional breeders. It's a good idea to raise silkies only in areas
that permit roosters, in case of an incorrectly-sexed bird.
