If there is a big disaster, does anybody have extra chickens in reserve?

Say if there is a large collapse of the economic system or transportation system or farming. Then I could survive better if I could grow some grain in my yard instead of useless grass, and raise some chickens. But I do not know where I would get the chickens from during the disaster. I know it would not work to buy grocery store eggs and try to incubate them, because they have gotten cold and died probably, and also they probably have not been fertilized by a rooster. I would have to have some kind of inside line to a local poultry farm, but I don't. Has any U.S. city, state, county, or the Federal government prepared a disaster plan which includes a source of chickens? Also, I am realizing a disaster plan can only do so much. Some disasters are really bad, like when a human comes and destroys and ant hill, and the ants just have to go off and try to find some other ant hill to live in. I probably would not have enough land to do very well unless I can outlive a few of my neighbors somehow.
