Reminder that Merek's disease vaccines made the virus worse and now people are dependant on a vaccine to keep the chickens alive.

They're fucking up the meat supply so more people choose to be vegan.

@pkvi What are your thoughts , having seen a poultry farm? Do they just need better sanitation?

Reminder that chicken shit is used as fertilizer.

When it comes to vaccinating livestock (and I now classify humans as livestock, having lost any privileges that previously separated them from other species) I like to point to Hendra vaccine for horsies.
