Most accidents happen either on the weekend or on the holidays. If your vet is not available, you need someone else to contact. Next, visit some pet shops that look clean, where the information is good, and where you are able to learn as well as look. Well perhaps not just yet. First lets do a little more homework.
Careful observation is the key.
Have a list of questions to ask and do not be afraid to ask them. If the answers are short or non-existent, thank them for their time and move on to the next shop. If a pet shop or breeder does not have the time to answer your questions, most likely they will not to be available when you have problems either. Many breeders now practice the closed aviary concept. No new birds are allowed into the aviary unless stringent quarantine methods are practiced.
