If the chicken head chopping tool was carried in a coat or a bag, they could get on trains and buses here. People aren't searched as they get on every single bus, train, or subway. They never have been.
My mother grew up on a farm and I lived on one in very young days. I used to help chopping chicken heads off. And I do remember when we had more than one running around without a head.

I also learned how to slaughter other livestock. No, it did not make me want to become a vegetarian.
Googling Chickens on public bus brought up links to a method of transport I'd never heard of before.
