I am so sorry to hear you are getting out of keeping pigeons Sourland - I know how much of a pain the birds of prey can be. My Rollers stand little chance against an experienced bird of prey, which is why I mostly fly them during summer months when the hawks are usually not around. Out of the breeds of pigeons I have kept the Homing pigeons have proven to be the ones which survive attacks from birds of prey, as they are overall swift, evasive, and tough little birds. I fly the Homers all year round with very minimal losses from birds of prey. It mostly depends on the breed, bloodline, personality, intelligence and physical capabilities of the individual bird.
... Have you by chance considered Parlor Tumblers or Parlor Rollers? They are a breed which cannot fly, are easy to care for and train, and both can be enjoyable for show, performance or just as pets.
