To set your mind at ease, please do check with your vet tomorrow. Your kitten will need to go in for vaccinations and spaying anyway, so it would be good to introduce her to them. I don't think she's ill because you say she's active and playing. As for getting along with her older sib, that will take much time and patience on your part. The older cat will assume the role of "boss cat" and will probably hiss at the kitten. Supervise any interaction and when you go out, it might be a good idea to put the kitten in a room by herself with a box, food and water until you get home just until you feel you can trust the 2 of them together. Kittens should have voracious appetites. That concerns me that she's not interested in food. Are you feeding her the same thing she was used to where you got her from? You might also try mixing it with a little KMR (Kitten Milk Replacment in cans at the pet store in the cat section) or Cat Sip which comes in a box that looks like a juice box.
