my conure has a beak problem and I wasnt informed when I bought her.
I guess you learn these things as you get used to having birds. I felt incredibly bad because I wanted to return her to her god awful overcrowded petshop..but I had to realize that a lot of animals have problems..and that shes lucky to have me care so much.
I would contact the breeder in a kind manner, do not return the bird (shes yours afterall- i would rather secure my birds future than get rid of her for a small problem)
My vet said aslong as she can close her mouth and chew her food things are okay.
yours seems to not be able to close its mouth tho.. I would take her to the vet and ask for help. ask how often you should schedule an appointment, ask about sliding scale fees, and ask if it can be corrected.
i was told that if they can chew millet, they are fine. i recently met a parrot with NO BOTTOM BEAK and it was happy as could be and ate from a syringe
