I think any precautions a feed store takes to help protect the chicks is good. Yes, keep them behind screens so every person/ kid with dirty, germy hands aren't picking up every chick in the bin. I don't want to buy a chick that's been held (and possibly dropped) by 50 people and their grubby kids. And I when I biuy a certain breed, its because that's the breed I wanted, not some mystery bird that got mixed up because someone put it back in the wrong bin. People just can't be trusted to have a clue about their actions.
Same with the safety of the chick. They are NOT toys to be tossed around or played with like in a toystore.
I wouldn't mind signing my name into a log book. Sure, its good in case something happens to the chick and you need a replacement, but its good to keep track of how many chicks a person buys and where they're going. I would question a person't motive and ability to care for 50 chicks if that's how many they are trying to buy. I think its important for them to protect themselves as well, like against that idiot who got salmonella. How do they know if those people were even customers at
TSC?
Maybe they shouldn't have put their fingers in their mouths or eaten after holding chicks. Who doesn't know to wash their hands thoroughly after handling livestock. OF COURSE they're feet have poop all over them and there is a chance of diseases being passed.
People need to learn how to be responsible for their actions and think about others who are trying to be responsible (
TSC) for THEMselves.
