Willing to travel reasonable distance to see and purchase. These phone numbers were taken out of Bird Talk magazine under breeders. I live in Texas, so I don't know if these are in your area, but these are the ones that said they breed amazons. Good luck, I have a yellow nape too. I have bought several birds from looking up breeders in bird talk.
Most breeders have better prices than pet shops.
They probably will all have babies in the spring, so you may have to wait. Ask them when they usually have their baby amazons, and call early. You could feed in the morning, leave food during the day, and feed again at night. Howard Voren has a good book on this subject. KayTee Exact has a good powdered formula for baby birds.
