I'm not a fan of inbreeding for racing however for stock yes. Last season I paired my current best racing hen to her father. However there is winners in all generation of this offsprings pedigree now, going back 4 generations. I then paired one of my best racing cocks to his mother again however there's winners in all 5 generations. The intention is then to cross the offspring of the said pairing. The hen is a Tasker x Lefebre Dhanen and the Cock is Gevaert Van Schoorise.
