Welcome to BYC. Actually none of them are considered good layers. Silkies generally do make very good broodies. When they are broody they will sit on eggs and hatch them, if they are fertile. Silkies are also one of the most difficult breeds to sex. Usually they cannot be sexed with any accuracy before 4-5 mos. of age, and sometimes not till they either crow or lay eggs. If someone tries to sell you a quaranteed female (or male) at an early age, walk away from them. Unless you don't mind being disappointed. Or having unwanted roosters that are difficult to rehome.
You may want to check out the "Silkie thread," just put that in the search box and it will come up. Loads of silkie photos and many folks with a lot of experience with the breed.
A great place to ask your questions.
