Adorable little birdy, and yes get the locks..
As a dog trainer I got into a tiff today with a random stranger who were trying to interact with dog I was working with with the owners. He didn't wanna greet the dog the way I told him to, telling me he knew what he was doing, I told him don't touch the dog and after that he had to count his fingers.. Good puppy... Some humans are idiots, and I dont care that he is on hard times, his stubbornness of not wanting to listen islikely what landed him there...
I have very little patience for foolish people, your new bird is unpacking, which is a great opportunity for training the right way.. and he may very well spoil that so be tough.. (Yes Im evil to humans)
