I was trolling around the ‘net looking for information on glass hens and I just have to point out this site – Fenton Hens and Roosters.  This is a very informative site about the methods by which you distinguish Fenton hens from those of other companies, or from reproductions.  Many photographs and lots of easily understood information.  Definitely worth a look.

While I don’t normally promote the sale of ‘stuff’, even my own – other than the link to my Etsy Shop – I might as well mention that you can buy an e-book by Shirley Smith called Glass Hen on Nest Covered Dishes.  It is a .pdf and sounds like it has a great deal of interesting information if you are interested in these items.
