I bought staightrun ducks back in May which is fine but 4 of the 6 ended up being male so I recently found some ducks on Craigslist all females for sale so I jumped at the chance to get them. I'm concerned about their feathers maybe it was their living condition but I'm almost certain the youngest has angel wing. I'm posting pictures. Any suggestions they're a little under a year old so I'm told and the girl with angel wing is 10 weeks.
