Great advise.What a sin! It looks like her head got bitten? looks like a puncture wound
It might be best to pluck the feathers away from both wounds, Rinse the wounds out with warm saline and water, And apply a triple antibitoic ointment like polysporin.
Is her eye damaged?
Try and get some pictures of both wounds
Best to keep her in a dark quiet safe place for now, a dog kennel in the bathroom or something
@Miss Lydia am i wrong?
