thanks for your reply! he's actually very quiet now which is great, he only crows in the morning for the cage to be opened up for light. I think it was summer affecting him because summer ends March here and he's very calm now. he loves the other male he's in with because they cuddle and groom each other all day. he really doesn't show any signs of sadness or loneliness. he's the fattest of them all because he's greedy with food. I was planning on get females but they are extreamly hard to get here in QLD as there's only 2 female to 7 males in each clutch normally which is bummer.
