Pigeons are a big part of my life. They are my friends and employees, providing me with nitrogen for
compost in their used bedding and they get
retirement benefits. When I want to limit the numbers I give the dog raw new eggs, but otherwise they are not for food, neither racing: just entertainment, providing a chance to watch the Cooper's hawk in action each mid winter.
I have three cotes and one is a 70s motorhome. All are protected with 1/4" mesh, and a livestock Akita-Labrador, who caught a weasel and a fox this year, a neighbor's cat last year (who resulted in a large vet bill for one of my old lazy cats) and a large raccoon before that.
They are also food security in a worst case scenario.
