My 11 year old daughter has two cockatiels they are babies and are in the same cage. It is my understanding that cockatiels are one of the few birds that can be caged together and still stay just as attached to their humans. My 14 year old has a linnie. They are both (or all three) wonderful birds! We have had the linnie for about a year now and we just recently got the cockatiels. The little linnie is adorable and will allow you to do just about anything with her. She loves to snuggle, shower, play! Great little bird in a little package, on the rare occasion that she has bitten it is a mean little bite, it hurts! She is small but mighty! Luckily she bites very rarely and mostly because she doesn't want to go back into her cage once she is out and playing with us! The new cockatiel babies are amazing! I am in love! I have always said that I was more of a bigger bird lover however these little boys have truly changed this! We were waiting for the lutino to be weaned and come home, while waiting there was a cockatiel baby returned to the breeder due to an assumed attack from the family dog. He came to us with no tail at all and missing feathers from one side of his face and the back of his neck. Well even after all that he has been through he is the most loving friendly little guy ever! I just love him! I am hoping that the lutino (the one we were originally waiting for) will become more "cuddly". He is very skittish and doesn't seem as loving! He is very young however and we are working on it! Sorry for the wrong post but I would vote for the cockatiel! I am finding them to be such amazing little birds!
