And just to point out, you are not going to get the biggest lines of those breeds from a hatchery.
The biggest and best lines of the biggest breeds are in breeders and exhibitors hands. People who have been sorting for type and size and the standard.
Not mass produced, hatchery quality birds. While you will get the rare very large bird from a hatchery it's an accident, not a purpose. Hatcheries don't breed for quality or size, so it's far less likely.
Enjoy what you have and if you enjoy them and they ARE what you want, add in breeder birds later.
Good luck.
