My Americanaa was attacked almost two weeks ago. I brought her in and for several days took care of her even letting her in the house So I would watch her. She seems to be recovering well , back outside and locked in the coop every night to avoid future attacks from whatever it i running around at night. (They are free range) She is eatting and drinking and active , but from the look of the injury I don't see how she will grow back any feathers? The skin there is completely gone, yet there was never any blood.
