English budgies are not as quick in flight as the American/pet budgies. Male E. make better pets. Most breeders of English breed for exhibition, so the stock they have for sale is at least 6 months of age or older. Even older cock birds can be hand tamed if the wings are clipped. These bird just don't put up as much "fight" as the smaller birds.
Some English can become sedentary and over weight. It is best not to leave treats at perch level, make the birds move around for their food/treats. If you can give flight time to your birds after you have hand trained (and their new fights have grown in) them that is GREAT.
Every bird is an individual. Each has it's own personality.
The exhibition part of this hobby is a LOT of fun! The competition and thrill of producing winning birds. You get to meet wonderful people from all over the U.S.
Be sure to ask for a pedigree on your new bird. Most exhibition breeders keep these records on their birds. They don't generally give them out unless a buyer asks for it. The pedigree with show you what colors are in the background of you bird. Though the band info, the breeder codes will tell you want aviaries the historical birds came from.
