Are you tracking her weight. Weight changes are a very sensitive measure of how she is holding up. If cocci induced scaring, then weight should come up within a couple of days of condition being stabilized. Generally, the ability to walk with heavy cocci infections is not lost unless birds is weak enough to suffer from hypothermia.. BE careful with the heat management and the recovery period. What you really need to watch for is a secondary bacterial infection going after your bird. Most treatments I have seen for poultry do not consider impacts of the secondary infection, When comes to that with bird I am trying to salvage I act prophylacticly. The bacteria in the GIT sometimes respond to cocci induced changes and start to cause harm and it can be quick.
