That's right, Daddy! Go away! I got what I wanted so now I don't need you anymore! They are extremely smart and often surprise me with their intelligence!
Please don't have your heart set on your being her chosen one. I know it's almost impossible to do this because we all want them to pick us but, with parrots, you really don't know who will become the 'spouse' and who will become the flock-mate. There doesn't seem to be a rhyme or reason for it with adopted birds because some of them will automatically attach themselves to the person of the same gender of the previous beloved owner but some will not. It's chemistry, just as it is with humans and falling in love... But, having said that, even when you are not the chosen one, it does NOT mean you cannot have a wonderful relationship with the bird! The only thing is that, if the chosen one is present, the bird will prefer being with that person.
I would not click and give her praise and a reward without their being a previous command and the bird actually acting on it. It's confusing... Think about it. What is it, exactly, that you are teaching her? Nothing! So why is she getting praise, a click and a reward? Mind you, not that I am against giving them treats for no good reason! As a matter of fact, that's what I do every day. I don't have training sessions, use a clicker, target, train for tricks or give rewards for something well done, I simply teach them what they need to learn to cohabit with each other and humans the same way a mother would teach a toddler: repetition, consistency, persistence and verbal praise [and, sometimes, a little scratch on the head but very, very seldom]. I am very relaxed with them and allow them pretty much anything they want to do as long as it's not bothering another bird, fighting or destroying something valuable [and the operative word here is 'valuable' because Lord knows they destroy stuff around the house on a daily basis!]. And it works like a charm for me and my birds - they are extremely well-behaved animals considering they are undomesticated and kept in an environment so very unnatural to them. They obey me better than my own kids did when growing up and some of the rescue dogs
I also have cats [I rescue dogs and cats as well as birds] and what I do is put them all in 'their' room [which, these days is my own bedroom because one of my sons and his family are visiting and using the guest room and the cats room which we 'transformed' into a temporary second guest room for my grandkids] where they have litter boxes, nice beds, windows to look out of, tall condos to climb and play on, different types of scratchies and I keep them there until it's time for the birds to go back into their cages [they come out when dawn is barely breaking -this time of the year at 6:15 am- and go back between 2 and 3 pm]. The cats don't mind at all and actually follow me eagerly into the room because that's where they get their breakfast [I don't free-feed any of my animals] - so much so that I have to be careful going up the stairs because they run in front of my feet
You might want to consider doing something like that... it's easier on everybody.
