So in my "gradual plucking" thread I realized that she had plucked the backs of her wings gradually and I hadn't noticed right away. Last night I found a big pile of shredded feathers on the ground, but she didn't really look any different so I wasn't sure where they were from. This morning she was taking a bath and I saw that she only has 2 feathers on one of her wings! She now falls like a rock and can't get any lift at all! I thought she was doing so well. I guess there was probably a "honeymoon" period with Beau and now that he's not new, he is no longer keeping her from plucking. I also think she is jealous because Beau is pursuing friendship with Maddie even though Maddie wants nothing to do with him and is very clear about that. I actually caught him trying to open Maddie's cage today to let her out! He wasn't strong enough to get the latch up but it just shows you how smart budgies really are.
