They will breed in our climate for ten months of the year, with the right attention. Very few hatchings are recorded during the two coldest months. Five or six eggs are the usual clutch, these being white in colour. Hatching will take place from 12 to 13 days. The young will stay in the nest most young are not self sufficient for up to 3 weeks.
Mature colouring is very slow.
They do like boiled egg but the egg must be boiled for 45 minutes. It has been proved that all bacteria in an egg will not die unless boiled for that period. Green food is readily taken with a preference for chopped green lucerne or comfrey. I have found that the Diamond has a tendency to carry excess fat if not given a large exercise area. This condition increases the worm problem in all birds.
