I'm new here; I have a question about a chestnut finch.
One of our baby chestnuts popped out with a black belly where they're normally cream/white. We read about the melanin phase that some go through which causes this and expected it to disappear after a couple of months. However, he's probably been around for about a year and a half to two years now, and is still as dark as ever, if not darker.
Any ideas???
(Now hopefully the photos work...)
