Hello. My daughter got 2 parakeets about a month ago. She takes very good care of them. They have plenty of toys, good food, treats, etc. She has been trying to train them and just spend quality time with them. Unfortunately, 1 of them has started biting her and the other wont let her touch her. What is She doing wrong? Or, how can we improve the situation? She is in no way agressive or loud with them.
