I have an almost 7 week old duckling that was a rescue. I have had it for a month now. I posted pics before and everyone was thinking muscovy. She is starting to get her feathers in and her coloring is making me think NOT muscovy. Any ideas? At 3 weeks And today. Chest is brown and black, the white collar has developed but not feathered yet. Underside is mostly white with some brown/black areas. And excuse the eye, she's got foamy eye which I'm treating.
