Then I would supplement to see if she improves, and add a feeder or two, spaced as much as you can, to try to give more chances to feed. Having some shelter spots, where she can kind of hide behind (make sure there are at least two ways in/out always so no one can be cornered) may help also. Stacks of blocks, pallets on their side (make sure they cannot fall or be knocked down), shrubs, etc all make good places to hide behind. Roosts outside that they can get up and away on. Just depends on your set up and how much space you have (the more the better-space also gives them more room to get away).
