That is another good reason! Looks It is quite difficult to tell the difference between male and female silkie chicks because they take longer to mature than most other chicken breeds; however, once they are mature, males (roosters) and females (hens) do have some distinct differences including: roosters tend to be larger than hens, the comb will be larger on a male than on a female, and males will crow while females will lay eggs. So far looks like a hen. What size is the silkie's comb compared to the roosters comb?
