I think the best way to keep the "pet owners" away (as opposed to breeders) is to establish the guidelines for conversation, requirement to use Std of Perf terminology and insist the moderators direct "pet owner" posts to the appropriate other thread locations.Won't work. The chicken mommies will invade.
I know BYC has been and wants to continue to be friendly to the "causal poultry owner", but a thread of this sort will only be as good as those who can be attracted to participate on a regular basis
