hi grasshopper lofts, as members have already told you the laffy daffy are lefebre-dhaenens which are short to middle distance birds up to approx 350 miles.....and as the game keeper told you are named after corn merchants roger lefebre and daniel dhaenens.
tha basic bloodline is desmet-matthys x roger vereecke, with introductions from beulque, m verheye and r verstraete.....
and as others have said, they also have stichelbaut in them.
i keep this breed myself and my stock are nigel cawood, jimmy richards and louella lines, below is a dark yearling cock bred from stock birds.......
