I'm so glad the boys are doing well! Super cute names and terrific that they are eating well. I bet Emerys will follow Caspar's lead and get braver. It hasn't been too long. I've never had a lovebird but I have definitely heard that they are opinionated.
At about 4 months old (maybe?) Gigi went through her first molt and she was a little nippy. She also lunged a bit when she was in her old cage when I changed her paper, cleaned her boing or put food inside. Now in her new cage everything is done from the outside so no reason to be territorial about her cage. She is a little hand shy, but not timid. She is very interested in people and gets as close as she can while in her cage. Yesterday the grandkids were here and she spent most of the morning on the floor of the cage, at their level. She is sweet, sweet, sweet. She jumps into my lap, races to my shoulder, preens my hair, nibbles on my cell phone and vocalizes like crazy. She has dozens of different noises she makes. I just love her.
