I found out about this during chick days where you fill out the forms when you buy chicks. That information that is passed along voluntarily to NAIS. Since TSC does this, I try not to buy there unless I have to. If I need feed and I'm over there, well it saves me 45 minutes from going to the grain mill. So I've noticed that i get asked for zip for non chicken related stuff, but with feed/hardware used in poultry they always seem to ask for my phone #....
It wasn't like I was going in there to give them a hard time on purpose, I gave them a phone number. It was one they recognized...... she should have left it at that without being snarky to me.
