As the.puppeteer said: Red head and Black head gouldians have red beaks when not in breeding condition. The hen's red beaks turn black when they come into breeding season.the.puppeteer wrote:RH and BH hens (unless the BH is YTB but I'm not getting into that lol) have red beaks when not in breeding condition that turn black.

If the hen has a yellow body then her beak will turn red or yellow in breeding season.
Hope that helps.
