Number 3 is definitely not a possibility Rocko is the boss of Loki and they live seperate and im always watching them and I dont know what u mean by thin feathering do you mean he has few feathers on his head and the bald spot only appeared today.There are three possibilities: 1) Rocko has always had a genetic bald spot and/or thin feathering on his head that you did not previously observe, 2) the bald spot is left over from his recent molt and has not finished filling back in yet, or 3) your new bird is plucking Rocko.
Honey coming home is nothing compared to when Rocko came home lol.I opened the box he was in a it was full of blood and it was all pouring from his eye in big lumps.Rocko might have knocked his head into something and lost some feathers. When Honey first came home, she flew into a wall and knocked out a small patch of feathers close to her eye. I was extremely worried but it turned out that she was fine, and the feathers started growing back about a week later.
Thats the reason why I brought Lokis cage to the petstore I was afraid the same thing would happen if he was in a box.Also im starting to think I have two female cockatiels they dont even sing only chirps.But males dont have to sing or whistle do they.Yeah I remember you mentioned that on another thread, that must have been very traumatic for both of you. So glad Rocko made it through that.
And I wouldn't worry about the bald patch. It should correct itself soon enough.
