Hi, so I have a 5 year old male cockatiel. The last time he has been with another bird was when he was 2 months old. I want to get another bird and was wondering how to introduce them (or if it’s a bad idea) Would it be better to get another male or a female (I am ok with babies)? The last batch of chicks I got I showed them to him and he tried to make friends with them so I think he would get along. Is their anything I should know?
