Chickens produce eggs and they'll eat whatever bugs don't have the sense to stay out of their way. Anything green and growing is fair game, too, so you've got to keep them out of the garden. Eggs and beans are going to be two key protein sources post peak.

The industrial farms won't survive and it'll go back to how it was when I was a kid. We'd get two hundred chicks at the beginning of spring. The males were promptly processed once they were large enough and a hundred surviving females hung out with one very busy rooster producing lots and lots of eggs. We sold a couple of dozen eggs a day at $0.50 a dozen after we'd eaten our fill. Their droppings were periodically spread on the neighbor's field, but I imagine those end up in my expanded garden going forward.

If the rest of the world can refrain from flying to bits I think things are going to be just fine here in the land that time forgot ...

Which is where? Just curious :)

Another thing you won't see on an industrial farm....
