As a buyer, I understand both sides of the coin. On the discussion of biosecurity, I was specifically told by one seller that I was not allowed to wear shoes that I'd worn in my coop or chicken areas, I had no problem with this, and used it as an education point for the kids. On the personal/chicken security, I respect a person's choice to not meet at home. Having said that, I really enjoyed getting to see how others keep their birds, and getting the opportunity to talk to them about their birds.
