Thank you guys. I know I haven't been on a lot lately, but I know I can always count on you for support. I really appreciate that. I just can't believe he's really gone. I cleaned up his burial site today and gave him some millet and pretty flowers. It was 3 am and I couldn't do too much for him. That made me feel a little better. He's buried with a feather from each flock mate.
I am keeping a close eye on the budgie flock. Alex is definitely looking for him, but she is still eating and flying around. I gave her some water in her favorite tub today and she did bathe. I'm sure she's not happy with me though as I have now started my frequent budgie body checks. Everyone felt good. None were very pleased with Mommy. I'm also a little surprised that Phoebe has stepped up and has been hanging around Alex, in a nice way. She's actually sleeping next to Alex right now. I hope it's providing her with some comfort. I'm glad that she has the flock for support.
I don't know if Sam, Joey, and Sydney know he's missing. They are acting a bit different, but I think it has more to do with me being upset. They don't interact much with the budgies since they are so much bigger and could injure them.
Thank you guys again for all your kind words and support.
