Both Popcorn and Muffin's *gotcha day* was Sept. 4, 1999. I don't know their exact birthday, but we were told they were 2-3 months old when we brought them home. I believe Muffin was a bit younger than Popcorn, maybe by a month or so, because she was so little, and even had a funny *chick* voice, which she grew out of when she got older. They were so tiny when we got them. I remember everyone coming to my house and saying they were so small for cockatiels. That's because they were babies! Now when I go to Petco, and see the young 2-3 month old tiels, I can totally see a difference. They look so much smaller then Popcorn and Muffin. We believe their birthdays are either in June or July........
