I personally wouldn't. If she's intended to be a breeder, it wouldn't be the best choice. Her weight is extremely low. She'll never make 1500 grams by age 3, and possibly not even by age 4, at that rate.
If the deal was 'too good to pass up', I might put her into quarantine, and have an immediate checkup done for parasites. Irregular appetite can often be due to parasite infection, and with a live-only eater, the risk is even higher.
