there are a boat load of bad breeders and a only a handful of good ones!...I like to think I fit the later, ha ha.
since I live in Canada, Ontario actually, maybe I can refer you to one, unless your in another province.
were you looking for a particular type of bird/parrot?
Since I breed I have to buy my birds then raise chicks. for me there are a number of things to look for:
cleanliness/safety measures
how the breeder interacts with you and the birds/chicks
I ask many questions about the breeders practices, and about the parents.
Feeding is highly important, do they just feed them seed, or pellets?
do they feed them vegetables, and other types of proper foods?
are they vet checked? How long have they had them?....any illnesses?
the list is extensive.
many breeders WON'T tell you they've had issues.
if they don't show you the parents of the chicks, go elsewhere.
don't let them come up with excuses either.
basically go by your gut instinct, if it feels right, great, if you are unsure of anything, walk
