Mine are all still pretty young. I hope they will start in the next year or so. I'm sure their are some nice breeders out there, just do your research. You will enjoy them.
I would suggest starting off with Black swans, they are better with other birds then some species, less costly and mine seem very interested in what I am doing. I would suggest you be careful if you buy here in FL. There are a few breeders that are either very over priced, have poor birds ...
