It depends...how old is she? Are you feeding her a variety of feeders or the same thing all the time? If she is maturing they will eat less than when they are babies are juveniles. Also, they will get bored with the same feeders and even go on "hunger strikes". Lastly, they will slow down on eating or quit altogether if they are ready to lay eggs. I don't know if any of these apply to your situation, but these are just some of the possibilities.
