I realize the US has primarily bantam sized Silkies. Does anyone in the US have standard size Silkies, or even larger sized bantam Slkies? Also, how often can a Silkie be expected to lay, per week, during laying season? Is it possible for a small Silkie flock to feed a medium sized family with eggs? Or, are Silkies really just ornamental and for show, as opposed to egg layers. Of course, I realize Silkies won't lay like a Heritage breed, or a production hen, but would a flock of perhaps 10 Silkies provide a family of 5 and the in laws with enough eggs to eat? Also, if it makes any difference, we prefer bearded buff Silkies.
