Keeping a Victory Garden and having home produced eggs are really old traditions, and not some new fad.  Here is an old patriotic propaganda / wartime advertisement from 1918.  Apparently, Uncle Sam expected everyone to all have backyard flocks of hens and raise chickens.  If we still followed Uncle Sam’s recommendation, my family should have 8 chickens!

To see more patriotic propaganda, war garden, victory garden, women’s land army, and more vintage posters from the early 1900’s , here is a good link:
