This saying is used nowadays to describe someone who is scrouging or trying to get something for nothing (what we call a ‘cheap-skate’). It goes back to medieval times when the Lord of the Manor used birds of prey for hunting.
The frame on which a falcon was carried was a ‘cadge’ and any of the tenants or peasants who were given the job of carrying the cadges all day, were thought to be doing very little for their day’s wages.
This is again from what I had got from “By Hook or By Crook” by Tony Wootton and Gwen Zanzottera. It is certainly a very short description but then you are getting something for nothing. Don’t get offended, I’m only joking, okay?
Come visit again. Thank you.
