Are French hens truly French?
With regards to the Christmas Carol: The three French Hens probably refer to a variety of chicken from France. There are many varieties of chicken and in the period during which this carol developed there were three main varieties of chickens associated with France. These were the Crevecoeur, Houdans and the La Fleche. The fact that they referred to a French rather than an English variety of chicken may be an indication that the carol originated in France or the words French Hens may have just had a good sound.
