Welcome and thank you for assisting this bird! If you could post some pictures of the injured foot and wing, that would be very helpful. It would also be helpful to know where you are located in case we have a member nearby that could assist you.
Basically, a broken bone needs to be set as soon as possible in order for it to heal back in the proper position. A week is quite awhile for a bird as they heal very quickly. Hopefully any breaks are already healing in the right position, but the photos would be really helpful.
