Chickens and Judaism

I went on a visit to a synagogue today.  I thought that it would be impossible to make a link with that and chickens, but this is not the case.  Mr Webber, the lovely man that organised the visit with his equally lovely wife, brought up the subject of chickens.  All the scrolls used in the synagogue are hand scribed in Hebrew and are often scribed using a quill.  Apparently chickens' feathers are too soft for this purpose; they tend to use goose feathers instead.  So there you go; the link between chickens and Judaism.
