BQ is overlooked a lot in the hype over SQ... most BQ is labeled as such by the more knowledgeable and honest breeders that just don't show their stock... culls are culled for a reason, but someone selling BQ means they'd use them in breeding but just don't need them as their others are slightly better or they have too many too keep all of them...
*this is a general rule, btw... there are still dishonest breeders out there that will use anything to sell off their extras, but odds are if they care enough to make a distinction then they're more reliable...*
If she doesn't get a couple Silkies this round, she'll get more in Spring...
