So yeah, let's vaccinate the birds.
(I saw something about why Canada doesn't have the same issues with the bird flu currently and it came down to smaller farms for a smaller population and more regulation. If that's the case, I imagine vaccinating the birds is honestly pretty cost-effective for the US, because if one bird gets sick, the loss of the whole farm's chicken population is significant on a whole other level.)
Agreed that it's a ridiculous way to show dominance and it doesn't do a single other thing but show that you're a terrible manager and workplace bully.
