As long as it doesn't contain too much added suger or is artificial, it should be great for her. Orange Juice is practically oranges, and fruits and veggies are an important part of a bird's diet. My birds LOVE veggies, but they don't like fruits, so I give them juice every now and then to make up for them not eating fruits. The only fruit they will eat is grapes, but they love juice. Let your birdie drink orange juice if she likes it. Its good for her.
