My white racing homers are a lot larger than king pigeons seen. birminham rollers are best starters, as fun to fly n breed, easy to train (extremely friendly), and great varying coloring n patterning, they need very little space and take confinement best and crowd n breed in piles in corners if not given nests n more space, eat less than any other breed especially less than any flyin n performance breed (fliers can maintain on wheat alone, until winter when corn good for cold, though good bird seed n chicken feeds). Parlor pigeons cannot fly after three months, n they are best pet pigeons for children. homers/racers, are all around great n breed. all of performance and show, flight breeds of pigeons are great as they have very unique look, coming in "capped"/crested, n "plain head", "pearl eyed", clear smooth cere/nose, etc.
