Save Kitchen Waste for Hens, vintage image courtesy of the UK Imperial Museum Sorry for delay in posting.  I thought I had this on automatic and then went to the farm and realized it didn't post when I got back. This one is another fun one.  I have posted a couple of similar posters with this same theme, but both of them related to saving scraps for pigs.  This one asks people to save scraps for hens (but mentions pigs in the caption).  It dates to WWII, the 1940's of course, and comes to us from the UK.
