First you need to identify what kind of turtle she is. Does she have red markings next to her ears? If so she's a red-ear slider, and she'll do fine on turtle pellets (yes, they are different from fish food). If she's a terrapin (you should look up a picture for that one) she will likely need a different type of food. I'm not familiar enough with other types of aquatic turtles to tell you about any others, you should look up pictures on Google to identify her species and find instructions for her care.
It may not be about her food. Does she have a place to crawl out of the water and get completely dry? That's VERY important for aquatic turtles, especially red-ear sliders. Also, what kind of light do you have over her tank? She will need a special UV light made for reptiles, so that she can bask and be healthy. A regular light will not do, and it should be over her tank but not right on top of it so she can't be hurt by too much heat.
I hope you find out what is wrong, if worse comes to worse you can call a pet store and they might be able to help you. Also please speak to whoever got the turtle for you and tell them that animals as pets are usually a bad idea, unless the person they're given to is familiar with the animal or explicit instructions for its care are included. Otherwise things like this happen. It's good that you're looking for the answers to properly care for her. Don't give her chicken, though, it's probably not good for her, no matter what kind of turtle she is. I would suggest regular iceberg lettuce for now, maybe a worm to see if she's carnivorous.
Good luck, I hope she makes it.
