YIW That story about those chickens dying in the heat is terrible and certainly things like that must stop.
I do not think that means that all places where kaporos are done are automatically guilty of such cruelty.
Similar charges have been made against meat processing plants
and yet within the frum community, we don’t have large numbers (if any at all) saying we should all stop eating meat.
Remember how easy it is to smear all Jews as “dishonest” because of Bernie Madhoff and a few smaller crooks who happened to be Jews, did such things.
So I would not be so quick to believe everyone running a kaporos place is necesssrily wrong, or that those who do, mean the whole concept must be wrong.
