Gouldian Finch Breeding

Gouldian Finches breed readily both in colonies and as a pair in a cage. Provide them with either open or covered nests. Nest boxes, larger than those used for Zebra or Society Finches, should be about 6"x 6"x 6" (15 x 15 x 15 cm) and mounted as high as possible. Both birds will build the nest and they will need nesting materials such as soft hay, sisal, and coconut fiber. Incandescent lighting tends to produce mostly males, while full-spectrum lighting helps produce a more equal number of males to females.
Provide soaked seed, egg foods and spray millet when breeding. Gouldian Finches need more protein than other finches to stay healthy and it is especially important when the female is laying eggs.
