Another floor in your master plan is there are a lot of fanciers who keep birds for pleasure, don't race, are not members of clubs etc, who would check them and how would you suspend them?
It is the non racing members that are prob keeping birds that may or may not belong to others!
Also i have spoken to many bird rescue centres that have always got racing pigeons in aviary's belonging to members who can't be bothered to send for them, should these centres be closed down because the unions do very little to deal with the owners?
