> 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.
