Great progress. It's always one day at a time with greys, and never fast enough for us (me anyway). So happy to hear you are working your way back though!
Timber loves a good face scratching and looks forward to sitting on my arm every evening before bed. I hold my arm close to my body and he sticks his beak down on my stomach and lets me have my way with scratching all around his face and neck. However, any other body part is taboo. Also, it's always on his terms. If he doesn't want to cuddle (rare but it happens) he goes in his cage at bedtime instead of coming toward me. Woe be to me if I attempt anything he doesn't want.
Time to face facts, time to do what is right. Get yourself a little perch for the side of the desk with a platform for your keyboard. The battle is over, the desk is Dorian's. The sooner you accept this, the happier you will be
You shouldn't feel bad. The reason we rehome is to give the bird a loving home where they can be comfortable, healthy and happy. As Jeff said, it sounds as if CC needs to be an "only child" and that's the type of home that would be best for her.
Hello and welcome to you and your flock! As to how greys tell the difference in human gender, I really don't know. That's an interesting theory you mentioned.
Hello and welcome to you and Dooble! My TAG, Timber is 9 and we still don't know if he is a he... You won't be able to tell by looking, the way to find out is bloodtesting if you need to know for sure.
