I do not know much about these birds' nesting habits. I really like them. These birds are beautiful conures but seem to lean a bit more toward being like macaws in personality and character. Many pairs will use a wooden cockatiel nest box, which I still use for some of my pairs. I also use boxes a little deeper, about 18 inches deep, and that works well for them, too.
Pairs usually have one or two clutches a year of around three eggs each.
Blue crowns make excellent parents. If you want the chicks for pets, babies should be removed before they are 4 weeks old for hand-rearing. These babies are very friendly, love attention and make great talkers. I have no problems getting my hand-feds off to their new homes. Stores always seem to be want blue crown chicks, since they sell quickly and stay very tame even after they are weaned.
