> If everyone in the world becomes vegan, what exactly do you think is going to happen to all of those domesticated cows, sheep, and chickens? Are people going to continue raising them as pets in the same quantities, out of the goodness of their hearts? Of course not -- they would basically go extinct.
Maybe they’d be put in zoos?

I googled "How many zoos in the world", and got an estimate of about 1500. If every single zoo had 10 chickens, that would make about 15,000 chickens in the entire world. I think going from however many millions of chickens there are worldwide down to 15k would count as "basically exctinct".
Far, far more than millions of chicken. According to this NY Times article 23 billion alive at any one time. [1] The most numerous bird species in the world.

People might also keep them as pets.
