Hello, my female African Goose acquired odd white spots on her beak yesterday morning and I don't know what they are or how they got there. She is less than a year old and her beak is usually completely black. It is snowy and cold outside, so could it be that she is too cold? I am new to owning geese so I would not know if this were normal or not. In the picture I circled two of the spots. Thanks!
