The Finch Information Center warns that hand-rearing baby finches often does not end in success, and is very time-consuming and tedious. If the baby does survive, its behavior as an adult towards other finches may be abnormal. It is preferable to try to find foster finch parents to try to raise a baby. If foster parents are not available, hand-rearing may be the only option.
The Finch Information Center recommends buying Kaytee Exact hand feeding formula, an incubator and a thermometer at a pet store. You also need infant applesauce, unflavored Pedialyte, flat toothpicks and soft cloths. For feeding the bird, you need 1-cubic centimeter needleless syringes and a short thin tube to put on the end.
Construct the brooder
Set up an incubator using a reptile box and heating pad from the pet supply store, lined with soft cloths. Change the cloths regularly. Unfeathered chicks should be kept at around 90 degrees Fahrenheit. The temperature should be slowly lowered as the chicks develop feathers.
Prepare the food
Follow the label on the Kaytee hand feeding formula exactly. The preparation varies by the age of the bird. Use the syringe with attached tube to gently deliver food into the crops of begging babies, or use flat toothpicks to deliver food into the beaks. Chicks should be fed approximately once an hour during the day and once every four hours at night.
Maintain excellent hygiene
Baby birds have weak immune systems. Wash your hands thoroughly, sterilize all utensils and discard all excess food preparations promptly. If the birds do not seem to be doing well, mix the Kaytee formula with the applesauce in a one-to-one ratio and feed that for a day instead of plain formula.
