Hi Farrah, glad you decided to join the family. Congratulations on your new baby grey. I'm assuming your grey will be fully weaned when she comes home. When I brought my baby home at 4 months she was about the same size she is now. She has filled out but is basically the same size. She has always been in her same cage, 32" x 23" x 37." She is comfortable there. With lots of room to flap her wings and climb all over the place, although she is out of her cage most of the daylight and early evening hours. Please ask all the questions you have and read the information that is in the nursery room, I have always found this forum a valuable place to be. Welcome to the family!!!
