Hi Barb, birds can be funny about the humans they "choose".
Several years back we adopted an umbrella cockatoo who was
supposed to be MY bird. Well, that lasted about a week. She fell
totally in love with my husband and only wants attention from me
when he is not in the room. They are smarter than we realize and
definately have personalities of their own.
Definitely let an avian vet or knowledgable pet shop clip her
wings. If is tricky, especially on small birds, and you could do
Good luck with your little 'keet!
