I show my expensive birds at the fair. I started with Komorners which i love. It will be best for you to find a breeder, perhaps one in your state. Purchase a pair and have them shipped to you. Ask plenty of advice from the breeder and take the advice to heart.
If you cannot find a breeder that raises Satinettes close to you it may be best to purchase what you can find and start from their. even a couple of crossbreed pigeons would work. Get used to raising them and familiarize yourself with their care. Breed them for a year or so and get to know that experience and raise your own babies. Then, when you have the time and the money purchase a pair of Satinettes.
It is best to start with what you have available to you and then to venture out from their.
