I rescued 3 geese from the park a few weeks ago-- 2 Africans, and one that I suspect to be a pilgrim or toulouse x african. The latter has a case of Angel wing, or twisted wing tip.. either way both her wing tips seem tipped upside down, and all her big wing feathers were ratty and dead when I brought her home. I trimmed them off to make her more comfortable, but is there anything else I can do to improve her condition? Is it causing any pain for her?
