I have a peer grey cocktail, male no cheeks, 3 years old and the female with cheeks grey three years old as well. I tried putting a nesting box in their cage, and they didn’t go in it the very sweet the male is calm and let you grab them most of the time and the female likes to be her own boss. She will fight to your head multiple times today. If you have kids, it’ll be pretty cool. Because she’s just flying at your head so fly to your shoulders sometimes they’re very nice cage you have to screw in one of the corners. Other than that it’s pretty new.
