I'm from Brazil and a have 2 cockatiels, they're male and part of the family... They always free with a big room and have a lot of trees in the house to fly around, because of that, we're always together. My older tiel, with four months always scream for my daddy and know he is no letting me and my boyfriend touching him, always when we're all together he flies to my father. I'm afraid cause he's very young. What can I do? Is that normal? Thank u all you guys and sorry for the bad English
