Biosecurity - People Security

I sometimes list chicks or adults on Craigslist and Facebook when they are ready for new homes. I've encountered some "interesting" people that way. Generally they ask fifty questions and want to see fifty pictures and then go ghost.
Why..why pester someone and waste all that time when you were never serious about buying anything? They will also usually want me to take less than I'm asking.
I never let people come to our home unless they are someone I know well, or are local and right down the road. I've had people get extremely offended when I've said no I'm sorry, you can't come to my home, I will meet you in a public place.
Now being on the buyer end myself sometimes, I understand wanting to know that someone is keeping clean and healthy conditions. I gladly show pictures and videos of my coops. But, the world we now live in is too crazy and dangerous to give strange people your address and let them see exactly what you have, and exactly where you have it. Seeming tire-kickers have went to sellers homes to look at livestock, said they would think about it, then came back and robbed the people blind..their home AND their animals!
Nope, I won't do it, and if that offends someone, they'll just have to move on.

There's also the issue of visitors who have chickens, unknowingly bringing disease in on their shoes, clothes and hands to your birds. That's also why I've all but quit selling at swaps. Someone handles several other chickens,  then wants to handle yours..not good.
It's impossible to avoid all risk of disease unless your birds never get out of an indoors barn or coop because wild birds also carry some disease that can spread to chickens and waterfowl. You can also unknowingly bring disease home on feed bags but...we can at least use common sense and do the best we can to avoid sicknesses, which includes always quarantining new chickens for 30 days.

Biosecurity and people security.
