Breeding and Hatching
It is probably a good idea to start with the easier species like Mandarins or Carolinas. Once you have a feel for it then purchase whatever species takes your fancy.
The important thing is asking around and select a breeder that has a good reputation. Once found then go and see him or her. Make sure you buy young birds. The problem with not doing that is, we found, that breeders will sometimes try to sell you their old birds. These may no longer be able to breed, and it will set you up for a loss.
