Molting

When birds molt, they require more nutrition such as vitamins and protein.  For gouldians, it is even more so since they tend to molt all their feathers quite rapidly - compressed molt - as long as they have enough nutritional resources.  Providing great nutrition, however, is definitely worth it.  You will be rewarded with birds with much deeper color and bright/sleek feathers.

 This is a red headed lavender breasted double factor yellow split to blue back male.

 This is a black headed white breasted single yellow factor blue (i.e. silver) male.  He had lost a lot of head feathers during bickering in the breeding season, but these have grown back nicely.

 Here is a red headed purple breasted single factor yellow back (i.e. dilute) male.  Note the grey bib and lime colored back feathers - these are much deeper in color compared to last year after I improved their nutrition.

This is the baby gouldian I've been handfeeding.  It's still quite tame; this will likely pass after I turn it loose into the flight with all the other junveniles where it will learn how to be a gouldian.
