Thank you reaching out to Ask Lafeber. To find ethically bred, well-socialized baby Severe Macaws with a health guarantee in New Jersey, start by connecting with bird communities like The Real Macaw Parrot Club, where members often know reputable breeders personally—this is one of the most reliable ways to avoid scams. You can also visit specialized bird stores such as World of Birds, which focus on parrots and may work directly with trusted breeders, but always ask where the bird came from and request documentation. Avoid buying from breeders who only sell online, won’t let you visit or video call, or don’t provide a written health guarantee (at least 7 days is standard). In general, a good breeder will be transparent, allow interaction with the bird, provide vet records, and ask you questions too—so your best strategy is to use clubs or reputable stores to get referrals, then carefully screen the breeder using the questions you learned. If I can further assist you, please reach out.
